It's depreciated by PEP8 to assign lambda functions. They are mainly used for stuff like this: tuples = [(1, 5), (1, 3), (1, 4)] tuples.sort(key=lambda x: x[1]) print(tuples) OUTPUT: [(1, 3), (1, 4), (1, 5)] For 1 line functions do: def add(a, b): return a + b

[@tobiaswegener1234]

Interesting thanks for the info!

[@TheJobCompany]

It's against PEP8 to not put a newline after a ":", so you would have to do it in 2 lines.

[@TimoKvapil]

I know that this might be a stupid question for you (I AM A BIG NOOB) But is it possible to recreate this sorting thingy, without actually using lambda. I mean using only functions. (we can't use lambda at school)

[@M15t4r1pP4]

Timotej Kvapil Depends on what you mean. If you’re asking about sorting a list using the key parameter and a lambda, then yes, that is doable.

[@soundcore183]

lambda can be used in commands for gui elements adding values without to specify a global function. Look at it like a list comprehension inside a function taking x and making basic operations without a function name. The difference to def i think it doesn't create an object or dict in general for exuting the function header like calling eval. Most of the object types in python are hidden dictionaries. Generators and annotators weren't mentioned.

[@baphnie]

Don’t fall into the trap of rating code by counting lines (re: list comprehension). Your code ought to be efficient, but MUST be readable. The best code is that which future peers can read reasonably quickly.

For Windows 10 using PyCharm with Python 3.7.6 , when you initialize a virtual environment "virtualenv venv" in PyCharm Terminal on your project, new folder containts "Include,Lib,Scripts,tcl and Readme.txt" , no /bin/. What you can do is cd to Scripts and then just type "activate" . should do it.

[@givdb5513]

Excellent vide, better than the majority of KZbin videos. What I really need actually for now it's a complete semantic, syntax explanation of Python and languages in general

[@CordonbleuZz]

List comprehensions are very powerful! i've seen it in Haskell (functional programming language) where you could write quicksort in 2 lines

[@chaddaifouche536]

List comprehension actually originates from Haskell, Guido was inspired by its syntax (and adapted that to Python). Of course list comprehensions in Haskell have their origin in set comprehension in Mathematics.

[@wouldbealex]

anaconda with a jupyter notebook makes debugging in-line. Then the code can either be run externally against the notebook or export the code to a py script. Conda also allows for multiple environments. With each environment, the developer can install whatever is best or required for that environment (e.g., _r-mutex and r-base in one env and Microsoft MOR in another without conflicts between libraries/packages. Otherwise, great starter video. Dictionaries or any other form of collection that can be traversed without array interactions is really important in all languages. Lamda and filter are great!

Good evening. I would like to ask how did your journey as a front-end programmer start? What does one need to do not in terms of knowledge. I try to get acquainted with programming but I can not understand it. I feel like I know nothing while I have been studying for hours!

[@atrus3823]

Good list, though I find I pretty much never end up using lambdas. The syntax is so verbose, and not that clear, and for most list operations, a generator expression is shorter and clearer. For example (x for x in [1, 2, 3] if x > 1) is clearer and actually shorter than filter(lambda x: x > 1, [1, 2, 3]). I tend to only use map and filter with regular def functions that are already defined.

Strings have the startswith() method to check the first letter. And you can also do set comprehensions, which use the curly brackets just like the dictionary comprehension.

I’m a python beginner coding on Mac OS. What program are you using to code python? Currently, I’m using a text editor (sublime text) and then using IDLE to run my code. I also don’t like using IDLE because it’s not that convenient as sublime text. It’s not very efficient because I have to keep switching back and forth. The program you’re using seems to do everything.

[@JakeCallahan]

Use vscode. iirc it is available for Mac as well. With the extensions, it is the best free editor/idea imo. Also, if you're experimenting with python, use ipython instead of the idle. Ipython is much nicer!

[@alikaperdue]

@4:58 -> perl doing python list comprehension @fruit_names = map($_->{name}, @fruits); Syntax is a little different, but the meaning is the same. Perl can collect data from structures in one line too and before python. Data structure would be nearly the same: @fruits = ( { name => 'apple', price => 20}, { name => 'avocado', price => 10}, { name => 'orange', price => 5}, ); For only fruits beginning with "a": @fruit_names = grep(/^a/, map($_->{name}, @fruits)); For a new dict using names as keys and prices as values: %new_fruits = map(($_->{name},$_->{price}), @fruits); Perl is old stuff now, but it had some cool features. I'm glad to see Python implementing and improving on Perl ideas. But "list compression" is just a name for something that appears in other languages without the moniker. Or it exists in Perl without an official name. We called these things: "one liners"

[@jordanrenaud7189]

A trick similar to the first one is to import your other programs and then call the functions like, import main; main.add(1, 2)

[@Kinos141]

other 'programs' are called classes, if I'm not mistaken.

[@jordanrenaud7189]

​@@Kinos141 This was a while ago I wrote this, but no I wasn't referring to OOP (object-oriented programming) if that's what you're thinking. I meant something more along the lines of writing and importing your own modules/libraries. This could definitely involve importing classes from other files, although I'm not sure I'd necessarily call these "programs" in and of themselves, more like components of a program. Instead of typing something like 'python -i main.py' to enter the interpreter, you can just enter the interpreter normally and 'import main.py' (the same way you would import any other module/library, like pandas, numpy, or os). It's just another way of doing the same thing; although I believe you have to be in the same current working directory as that file (main.py) or else specify the path in your import statement. I love the modularity of it because you realize you can write your own libraries/tool kits. You could define all your classes in one file and import/use them in the main program if you wanted (separation of responsibility, adding another layer of abstraction). I'm not a software engineer though, so I can't speak to best practices. I'm sure someone more familiar with OOP will correct me. I'm a data analyst and tend more towards functional programming. Again though, classes are components of a program. You still need to instantiate them to use them. They are not programs in and of themselves. You define a class and then create an instance of that class (an object), from which you can define it's attributes and call it's methods. I believe this is how it works anyway. Python is multiparadigm though, so you can do OOP, functional, procedural/imperative, or a combination depending on your style or use case. For example, ML (machine learning) tends to blend OOP and functional programming (the popular ML libraries are OO but the code written to implement them tend to be functional). If anyone knows better, please keep me honest. I'd hate to misguide anyone :-P
