I prefer everything that's got explicit variable declarations. it's clearer in terms of what parameters to give to a function. if i'm hacking together something quick in python and come back to it a month later i may have to check the correct way to pass params to that old function before i do anything with it, this is all "automatically" taken care of in something like C#, essentially forcing me to document my params at least a little bit

[@djpeterson7479]

Bear in mind that specifying the type of the variable in C# exists for a reason. It's there so that both the compiler and the code writer understand a variable is being declared and used. This comes in handy for catching bugs as a typo will cause your code to not compile. As opposed to Python, a typo will simply create a new variable and you'll have a logic error (typically harder to debug) instead of a compile time error. I'm writing my own scripting language and ended up switching from Python to C# style for this very reason. As a quick aside, in C#, you don't need to always specify the type when declaring a variable. If you are declaring and initializing, you can use `var` and the type of the variable will become the type of the expression. I'm excited to learn Python because of how terse it is, but honestly it represents a lot of the things I've been trying to run away from: non-strict variable declaration, dynamic type systems and a focus on mutability. After over a decade of experience, I find these things to be more of a hindrance than a benefit especially as your code base grows.

[@vivaleute5141]

@Shahar Erez you're talking nonesense

[@vivaleute5141]

@Shahar Erez It wasn't trolling. Man, do you know about architecture and prediction? When you're writting some code, you need to understand for which purpose and trying to predict what it will be in future. So it sounds weird to me, that it's much easier to use language without strongly typing. It means that you don't understand what you're writting.

[@zeppelin0110]

These 2 are my favorite programming languages, but I have to say, I think C# is the 'better' one. Yes, I know they are different and they are used differently (e.g. Python is more used by data scientists while C# is more popular in a business environment) - but I think C# is more modern and advanced. I will give just 1 example to prove this - Linq. While Python has list comprehensions and lambdas, and they certainly are powerful, they are nowhere as elegant and convenient as Linq. All that said, I do like both languages a lot, but have a slight preference for C#.

C# is a lot like Java but more powerful, more commonly used (again, except for android of course), less cumbersome, more performant and you can even program games in it (using Unity). The only successful PC game using Java that I know of is Minecraft, and that has constant issues with memory leaks and stuttering due to Java garbage collection.

[@QuantumFluxable]

@@omairtech6711 I suppose that depends on how far you got into Java already, but I've learned a lot of languages over the years and eventually realized that one can never "learn" a programming language fully, it's more like a tool: I'm sure you know how to use a hammer, but can you use it as well as a carpenter or a smith? probably not, but that doesn't mean you should never pick up a hammer, it just means you could be more efficient with it. Programming languages are the same, once you got the basic concepts you can use them to do all sorts of things, and while you do that you continue learning the tiny details and become better at using the language, but you never finish learning it. That's a super long way of saying "it doesn't matter as much what language you learn". C#, when first introduced, was being advertised as a Java that isn't Java. Basic syntax between the two is very similar, so it shouldn't be a problem for you to switch if you want to do that, especially since you used to program in Delphi.

First off: big fan; but there are some mistakes: The types are declared not cast Python doesn't need to declare variable types but not because it's Interpreted but because of it's type system which is dynamically & implicitly typed (while still being strongly typed I think?); Whereas C# usually is statically, weakly and explicitly typed (with Support for dynamic typing and type inference(recommended by MS)) If there are errors in this please correct me :D

[@SVVV97]

Also C# has a model that's similar to (c)python's: compile to bytecode or some IR and then be interpreted by a VM (where C# then is JIT compiled) afaik

I'm going to leave here, if you don't mind. If anyone wants to clear the output, type 'Ctrl + Shift + P'. It will pull up a window, then type 'Clear Output'. I searched for this problem, but didn't find an answer. Thankfully someone said to do it with the terminal, so I guessed if I used output instead, it would work. Also, save your code before you run it, otherwise it will run a previous save of the code. Or if you didn't save it at all, it won't run. At least that's what happened in my case.

[@FurryDanOriginal]

I'm not an expert and also no native speaker, nor very informed with the general programming terminology, so if there's anything you think is wrong, feel free to correct me. In fact I don't know most of the stuff but am making educational guesses instead based on how the discussed points in this video make sense to me. In C#, the reason why you have to give a variable a type and can't change its value to a value of another type is not necessarily bad (and not there because the language can't figure it out by itself, in fact there are ways it can which I will point out later) but rather a design choice. When declaring a variable as one type it barely ever makes sense to give it later on a value of another since one variable should always represent one specific "idea". And almost all of the time that one won't change its type since it's bound to it. If you want C# to figure out the type by itself you can just always use the "var" keyword which will make the variable of the type of the value that you're assigning it to. The only times you can't do that, as far as I know, are when you're just declaring a variable but not initializing it, or you're giving a non-struct object it's default value "null" since that could be valid for any reference type and couldn't be figured out just by the value a variable is being assigned to. If you want to use a dynamic type meaning it can change its value type afterwards, even though that has very limited practical uses with the main disadvantage being that the compiler has no clue on what type it is and therefore what fields, properties and functions it contains, just use the keyword "dynamic". That being said, I absolutely do love python for its syntax of not having to resort to semicolons and espacially curly braces. Since you want to format your code to be readable anyways, in my opinion it absolutely makes sense to merge the syntax and indentation into one to avoid much visual noise.

[@lucaswalker6919]

In my opinion it makes the code easier to read to have the curly braces and semicolons. Idk, I guess my mind just processes it wierdly.

Nice video! Hope you don't mind me saying that there's a couple things here that are not quite right though. Static typing in C# (i.e bool something = true) isn't the same as casting. Casting is where you implicitly or explicitly cast one data type into a different one (i.e something.ToString()). An "interpreted language" (like Python is) does refer to the fact that it "interprets" variable types. Instead, this behaviour means that Python is a dynamically typed language, rather than a statically typed language like C#. Static typing means that if string value = "Something", the variable "value" must now always contain a string. In Python, I don't think you can set types explicitly, and variables can contain whatever you want them to! Crazy town! An interpreted language is one that has no "build" step, like C#. Instead, a separate program called an interpreter will execute the code. C# is compiled into machine code and executed directly by the processor.

[@Po1aris100]

I don’t know much about C#, but I do know that in python every block of code doesn’t have its own scope. Scopes are defined for the Module, Classes and Functions. An if, while, for, with, try...etc block can initialize a variable assuming that block is evaluated.

[@NickTheHunter]

15:00 - the “a” variable was not declared because your “doit” variable is assigned to be false, I guess. Is not this the only reason for the error?!

[@crucifixxx4960]

That's true, but it will show the error anyway. The variable can't be used because its inside the block, which the code technically can't "read" outside the block. If you specifically set the variable to global then it would work.

I feel c# is very much richer in syntax. And the python is how kids are writing something on pre school. Why people are behind dat .c# and dotnet provide much more advanced out of box features already.

Just for some feedback, I feel like it would be helpful to make a video before this in the playlist that goes over some of the programming terms used in this video.

Those terms are in the playlist that's in the description.

[@moyk3517]

Why does it show the wrong number in the output if I change the variables. (For example, i changed the a = 5 in the video into a = 7 and it still showed 5). I can fix this by debugging but do I really need to do that every time? newbie here.

[@curtisbell2872]

That was extremely clear and helpful!

[@clemens5295]

maybe i misunderstood but as far as i know you can actually initialise a variable in one code block and read it /set a new value in another.. it just didn't work because doit was False, the if condition therefore wasn't met and the variable wasn't actually initialised.

[@RobAbdul]

With the greatest respect I disagree. In Python variables are traated as string when input is used and until you specify int, float or boolean -it is treated as string.

[@13MrMusic]

15:45 First you said C# when you meant python, second it doesnt work not because of the scope but because the bool var is set to false and the block didnt run. If you set the boolean to true and run the block then it will print the variable no problem. As far as I understand the scope of variables becomes an issue when working with functions.

[@crucifixxx4960]

It won't. Even if he set it to true, it wouldn't be able to use that variable since its declared in a block. If the set the variable to global, then it would work, but he is right here.

Hi, do you think JavaScript is good for a beginning?

[@Saleca]

I start using c# because of unity but I now think python is a better language, is that accurate? Knowing both of them is there a reason other than unity to keep using c# over python?

[@DevlogBill]

I am familiar with JavaScript and Python. Wow programming in C# is so much work? I was considering by the end of this year to dive into the .NET environment but watching your video I see that C# is so much harder than JavaScript. I struggled learning JavaScript I have a feeling learning C# is way harder, am I correct? How hard and long is it to learn the .NET framework and C# for web development?

[@TheMetalkon]

C# is not very complicated once you get used to it

[@DevlogBill]

@@TheMetalkon Thanks Metalkon, I am guessing for web development full stack the hardest part is learning .NET not so much the syntax of the language?

[@nickareekadan7313]

Might be a dumb question but didn't you set the variable "doit" = to False the second time so wouldn't the logic of the if statement be... doit = False Print ('checking...') if doit ( which is now = to False): doit = False Print("blah") Shouldn't it print the if statement because doit is equal to False? I think I'm just confused..

[@BiancaAguglia]

if doit actually means if doit == True (Also, keep in mind that doit = False means you assign the value 'False" to the variable doit, whereas doit == False means you're checking if variable doit is 'False. That can be a bit confusing when you first learn Python. ) If you want to understand this better, try the code the following three ways: 1. doit = False Print ('checking...') if doit: doit = False Print("blah") 2. doit = False Print ('checking...') if doit == True: doit = False Print("blah") 3. doit = False Print ('checking...') if doit == False: doit = False Print("blah") You'll see that ways no. 1 and no. 2 work the same. Way no. 3 prints out 'blah'. 😊 (You don't have to use doit = False inside the if blocks, but I left it there to match the code we started with.)

@@nickareekadan7313 Or you can put it this way, double equal sign, or " == " means "equal", which is used to check something. While a single equal sign, or " = " is to assign data types. As a newbie myself, I made the same mistake thinking that " = " means equal to.

Jabrils, Just finished watching your first four videos. Enjoying your content. I am attending Lambda School for Full Stack Web, but really would like to get a head start on Python and C#. I am also fascinated with Data Science and Machine Learning and enjoyed your other videos on those as well. I can say that after 11 weeks of full time schooling so far, that I still picked quite a bit up from the first 4 videos. Really interesting how C# and Python compare. I have been using mostly JavaScript, object orientated programming is familiar for me. What I enjoyed the most about your videos so far- Your content matches up with those you've done before, so A+ Teaching C# and Python side by side was a great experience Length of videos Where I think you should concentrate- Scripting your videos to have the biggest impact, you could really capitalize on keeping the same length for your videos and increasing the amount of depth at certain points (i.e. explaining an assignment operator, default lines inside of C#) The C# screen's font size could be larger, the = is pretty blurred Spend maybe just a bit more time on how to set up a fresh app for both C# and Python. Maybe just a quick revisit at the beginning of video #4 Can't wait to make my first program with the next tutorial! I will try and leave some more comments for you. Very excited that I decided to follow you on twitter. I have been watching your channels page like a hawk for new content.

in C# var is your friend if you assign it a value.

[@lythd]

This is the first video I've seen from you and I want to say that this was a very good video. I am a java developer but I'm looking for another language (just so i can more easily relate to other developers). I've coded a tiny bit in python and I was wondering if I should switch to C# and this video was very informative thank you! The only thing was that you used casting incorrectly, casting is changing a data type to another data type, an easy example would be an int to a float or vice versa, so like the random function (at least in java) returns a float but let's say you want to use an int you could cast it using *int random = (int) Math.random();* what you meant to say was just declaring the type. However since casting works the same way in C# vs Python (as far as I understand that might be wrong) I don't have a problem with it. Great video tho, I subbed and I can't wait to watch more of your videos!

[@Christobanistan]

Just to entice you over to C#, you can write a condition like so: if (a is < 4 and < 0) { ... } Really. It's pattern matching is pretty great.
