if anyone was wondering at 2:57:25 why the from_ parameter needs an underscore at the end, it's because "from" by itself is a reserved word in Python (used in things like from Tkinter import messagebox, for example). Using a reserved word to have a completely different meaning would be problematic, so the developers of Tkinter added an underscore at the end to differentiate it from the original "from".

not really i have seen myself that when people learn only one framework without any practice and deeper understand they will have a big problem implementing it in real life like learning python tkinter without knowing the deeper structure of programming language and all and then having confusion and intimidation with creating a real problem with it with sql / backened basically people can feel great by making calculator programs and great cheap praises from people who dont know this field but which will only make their skills at simple calculator level until they find it difficult too.

[@KavyanshKhaitan]

@@ceciljoel9577 first you atleast gotta make something simple. You can use the same principal for the frontend (few buttons, inputs, dropdowns, etc.) and apply it to anything. For example, some command line tools, a multi-PC manager for a school, etc. I personally am trying to apply this into some software that our school lab requires but is not available online. So.. yeah. You can use that same calculator and repurpose it for something much-more significant. Another example: my grandfather has trouble using the command line for programs i made but really wants to use it as it would be helpful for his day-to-day task. I could implement a similar UI and apply it to 'em.

Tkinter is not so bad... lots of documentation out there, and lots of example code to copy, try out, and experiment with. Essentially you need good problem-solving, and research skill, to get anywhere. I think what helped me is that back in school we spent a couple of weeks preparing for coding coursework and tkinter was something we covered way back then.

[@paultaylor7115]

note for around 1:02:04 when he decides to use a global variable: if you want to avoid using globals (and just make the whole calculator project a lot simpler), you could just have the calculator show the entire expression when you type it, instead of clearing the Entry field when one of the arithmetic operator buttons are pressed. This way, your program doesn't need to remember anything, and can just read what's in the Entry field when the equal button is pressed, and use eval(expresion_as_a_str) to evaluate the whole function easily. I'd also recommend making a function to create all the buttons so that you don't need to copy basically the same line a bunch of times only to change the value and placement of the button. Using partials (from functools import partial, then command=partial(myFunction, argument)) is also a helpful way to pass arguments to the button commands. With all this, the calculator project becomes a lot shorter to code and has all the same functionality. I wrote one that supports addition, subtraction, multiplication, division, exponentiation, decimals, and order of operations in 50 PEP 8-compliant lines haha, and I'm sure it could be done in fewer!

[@-heal4ever-]

Thanks for the help, i was new into tkinter and knew the eval expression, it just made it so easy. Gonna research on the partials function and will try to learn.

[@itamar2272]

[@emilnavod67]

Isn't the use of eval() considered a bad practice?

[@anirudh2000]

Or you could make a bunch of variables outside just for the purpose of storing temporary values. And instead of using global, change those outside variables according to your needs

[@nowybopes]

3:40:02 if someone has a problem here with *"AttributeError: 'NoneType' object has no attribute 'delete'"* Don't do l_name = Entry(root, width=30).grid(row=1, column=1, padx=20) but l_name = Entry(root, width=30) l_name.grid(row=1, column=1, padx=20) it works then

[@deathbottle06]

Hey everyone! At 3:15:19 you can type var.set("Off") or var.set("On"). Explenation: The checkbox does not set a default value by itself. When you make an IntVar(), the default value for an Integer (or number variable) is 0 which (to the checkbox) means false. So basically, you are giving the checkbox a default value, when you set the StringVar() to "Off". I hope this explenation was understandable. Have a good day!

[@xzex2609]

this video is greate , and it's very adorable that he really shows actual development , that a developer make mistakes and instead of cutting the video , he gets through it and really thinks what he should do to resolve the problem , it's very adorable and self confidential.

[@x0kosmus0x]

I watched the first 2 hours because I never created gui apps in python before. This tutorial seems to be good if you want to get an overview of the different widgets, but I have a suggestion for anyone who is following along: try to reuse functions instead of copying code and defining functions that do basically the same as the copied one. E. g. the calculator has four different functions that are basically the same with a different string saved in a global variable. You could pass the string as a parameter like you did with the number function, then you would only need one. The image viewer also has redundant code. You could call the same funktion for forward and backward, just put both if statements in.

[@aholder4471]

I'm new so forgive me if this is a dumb question, but do you mean to create a variable for each math operation, like add, subtract, multiply, divide and pass them through a function? So instead of having a line of code for each one, you can just define each one as a variable? I'm interested in this because my thought when I watched him build the image viewer is that the way he coded it was static, and I know it should be able to be done dynamically for lack of a better word. I know he did this to make it clearer and help teach the basic principles but I'm curious how you would call images without specifically referencing the specific image file. Can you call files without being specific like that? I'm sure it's possible somehow.

[@x0kosmus0x]

@Aaron Holder The more general function for all 4 operations could look like this def button_opt(opt) first_number = e.get() global f_num global math math = opt f_num = int(first_number) e.delete(0,END) And then you could call it like this button_add = Button(root, text="+", podx=39, pody=20, command=lambda button_opt("addition")) button_subtract = Button(root, text="-", podx=39, pody=20, command=lambda button_opt("subtraction")) button_multiply = Button(root, text="*", podx=39, pody=20, command=lambda button_opt("multiplication")) button_divide = Button(root, text="/", podx=39, pody=20, command=lambda button_opt("division")) the rest can stay the same and you save 21 lines of redundent code. For a dynamic image viewer you could use os.listdir to get all files in a directory. Then you could loop over this files to and create the image objects for your image list. The directory you check for images could come from user imput.

[@noelgomariz3038]

for the image viewer app, there is a simpler way to make the buttons work: create a variable "i" that will keep track of which image is actually displayed, it will be obviously initialized to 0. Then, inside the next_image function declare the global variables "my_label" and "i". Each time you press the button_next, "i" will increase in 1 until it gets to the limit of the list, time when it will go to 0 and start again the count. The same for the previous_image function. Hope I made it clear enough. image_list = [ ] # list with your images n_imag = len(image_list) i = 0 my_label = Label(image=obama_list[i]) my_label.grid(row=0, column=0, columnspan=3) def next_image(): global my_label global i i = i+1 if i < n_imag-1 else 0 my_label.grid_forget() my_label = Label(image=image_list[i]) my_label.grid(row=0, column=0, columnspan=3) def previous_image(): global my_label global i i = i-1 if i >= 1 else 2 my_label.grid_forget() my_label = Label(image=image_list[i]) my_label.grid(row=0, column=0, columnspan=3) button_previous = Button(root, text='', command=next_image)

For people who are struggling around 1:45:00 to get the '>>' or 'Next' button to enter a 'Disabled' state: He mentions it doesnt really matter where the if statement is placed. However, this is incorrect and probably just overlooked due to the recording happening etc. The if statement needs to be placed before the buttons as it will determine the state in which the buttons will be in. Once they are placed on the gui, the state can be changed but the button would have the removed and replaced. Similarly, we cannot place the if statement prior to us incrementing the image_number variable. The reason we cannot do this is because if we increment after the if statement is executed, then we will be able to use our button past our final point and encounter an error. At this point, the button is broken and will just keep producing errors in your terminal or console window. Ensure you place your if statement exactly where it is placed in the video to save yourself the pain of what I did and spent an extra 20 minutes on top of this 5 hour video trying to work it out haha!

Also for Mac users (I have never tried this on a Windows or Linux machine), to make the calculator buttons fill the space exactly like the one in the tutorial, you may need to set sticky='nsew' for each of the buttons if you use grid as he did (pack behaves differently where you can set expand to force widgets to fill the remaining space)

I think you now, at the video of the simple calculator, for the different operations, you could use the eval built-in function. Like the global math variable of each function is the corresponding operator. For instance: def button_addition: global math math = '+' So then, in the equal function you use: e.insert(0, eval(str(f_num) + math + str(second_number)) Thanks for the incredible content!

[@zackjandali]

The reason for setting command=myClick instead of command=myClick() is because “myClick” is actually a variable that contains the address of the function. “()” is the indicator to run the code stored at that address. It’s similar to an array and the subscript operators “[]”.

Here's the code: from math import ceil NUM_BUTTONS = 10 buttons = [] for i in range(NUM_BUTTONS): buttons.append(Button(root, text=str(i), padx=40, pady=20, command=button_add) i_row = 4 - ceil(i / 3) # this will give row numbers 1, 2, 3, and 4 where appropriate mod = i % 3 i_col = (mod + 2) % 3 # this will give column numbers 0, 1, and 2 where appropriate buttons.grid(row=i_row, column=i_col)

[@jeffholland4248]

Actually this places 0 on the right instead of the left, but this can be simply fixed: if i == 0: i_col = 0

This was an absolutely amazing course! I've been trying to learn how to make GUIs using different python libraries and this is by far the easiest route to take and the most comprehensive short course I've seen!

[@traeldor]

I would just like to say thank you for this video. While it is long, it is very comprehensive, and I have learned a ton in just the first hour. And without all the pickles, bacon, and belches. Thank You. I've been programming lightly for many years, and discovered python, while 2.6 was still the rave. 3 was just at the door, and to this day I still try to 'print data' and not 'print(data). hahahaha. I get Tkinter. Qt4 or 5 is easy enough but I like Tkinter. There is/was another GUI programming Style in C/C++, but I don't remember the name. Please keep up the great work. Looking forward to watching/learning the rest of it.

from 42:00 to 1:18:00 calculator, you can use following code: from tkinter import * tk=Tk() x='' def clicked(n): global x if (n=='clear'): x='' elif (n=='equal'): x=eval(x) x=str(x) else: x=x+n l1.configure(text=x) l1=Label(tk,text='',font=('Arial Bold',10));l1.grid(column=0,row=4,columnspan = 4) d0=Button(tk,text='0',font=('Arial Bold',15),command=lambda:clicked('0')).grid(column=1,row=3) d1=Button(tk,text='1',font=('Arial Bold',15),command=lambda:clicked('1')).grid(column=0,row=0) d2=Button(tk,text='2',font=('Arial Bold',15),command=lambda:clicked('2')).grid(column=1,row=0) d3=Button(tk,text='3',font=('Arial Bold',15),command=lambda:clicked('3')).grid(column=2,row=0) d4=Button(tk,text='4',font=('Arial Bold',15),command=lambda:clicked('4')).grid(column=0,row=1) d5=Button(tk,text='5',font=('Arial Bold',15),command=lambda:clicked('5')).grid(column=1,row=1) d6=Button(tk,text='6',font=('Arial Bold',15),command=lambda:clicked('6')).grid(column=2,row=1) d7=Button(tk,text='7',font=('Arial Bold',15),command=lambda:clicked('7')).grid(column=0,row=2) d8=Button(tk,text='8',font=('Arial Bold',15),command=lambda:clicked('8')).grid(column=1,row=2) d9=Button(tk,text='9',font=('Arial Bold',15),command=lambda:clicked('9')).grid(column=2,row=2) add=Button(tk,text='+',font=('Arial Bold',15),command=lambda:clicked('+')).grid(column=0,row=3) sub=Button(tk,text='-',font=('Arial Bold',15),command=lambda:clicked('-')).grid(column=2,row=3) mul=Button(tk,text='*',font=('Arial Bold',15),command=lambda:clicked('*')).grid(column=3,row=0) div=Button(tk,text='/',font=('Arial Bold',15),command=lambda:clicked('/')).grid(column=3,row=1) clr=Button(tk,text='c',font=('Arial Bold',15),command=lambda:clicked('clear')).grid(column=3,row=2) equal=Button(tk,text='=',font=('Arial Bold',15),command=lambda:clicked('equal')).grid(column=3,row=3) tk.mainloop()

fucking legend. I was having so many problems with this. I don't know why but at some point in the video it just stopped working for me although i did it exactly the same way. Thanks for this

[@pawlack]

In first task - making calculator we can use "eval" function that calculates formula from string. eval("(3+5)/2") = 4, so we can make buttons just append to string. This way user can also just type formulas in textbox and equals sign will calculate it.

1:39:47 my_label = Label(image=image_list[image_number-1]) actually we have to count from end. That why we use -1. because -1 count from negative index. All the best guys! Happy Programming!

[@medsmati2063]

Hello Mr John, I want to give you the explanation of the strange behavior of checkbutton when we use string value instead of integer value. the line of code concerned is: c = Checkbutton(root, text="Check this ...", variable=var, onvalue="On", offvalue="Off") when you used an integer value, possibles values are 0 or 1, and the default value for integer is 0, it is why by default it is unchecked; but when you used string value and you defined the values "On" and "Off", the default value for a string is an empty string "" which doesn't exist between the 2 values you choosed; that means that the checkbutton starts with neither the value corresponding to unchecked nor the value corresponding to checked. To correct this, we can initialize the string variable with, for the example, "On" (if we want it to be checked initialy) or "Off" (if we want it to be unchecked initialy). var.set("Off") cordially

[@vandinem]

Following the tutorial in Ubuntu 18.04, and have learned the following: Instead of "Lambda", use "lambda" (lower-case "L").

yeah, it's lowercase in the video too...sublime just makes it look sort of capitalized.
