Build A Simple Calculator App - Python Tkinter GUI Tutorial #5

Hey, why you have placed columnspan parameter and applied it on the Entry widget? The other (button) widgets inherit it?

Thanks u🎉

i wonder about lambda function , i never see to use function outside and use inside lambda , can anyone tell me how it work

width and padx button, how different?

how to fix Tlc/Tk error

sir my global variable aint working

How to make the tkinter window flexible when maximizing or adjusting the size of the window?

For python 3.10, with pycharm, in Ubuntu, it's lambda instead of Lambda.

i love this

Amazing

god bless you men thanks alot ❤❤❤

Hello. Its from Bhutan. This video really helped me. Kadrinchey!

Please continue to make videos, you are truly a great creator and help so many people like me learn to code

Thanks for the great intro to python. Can't believe my first project worked:)

Can you explain how to limit input to the GUI or easily exclude letters and non 'math' symbols from the keyboard please?

I´ve been trying to bind the buttons to keys on the keyboard, every time it seems to just type out all the numvers and they keys don't seem to do anything. Any advice?

any source code available?

sus

I enjoy how fun you make your lessons, 😃Thank you

Hello ! Could not we have created an Object "Button" instead of copy/paste all these lines ? Thank you

ONG

How’s it going?

how do you know to set the padx of "=" is 91 ???

Can anyone write the code in the description

Great teaching ! This playlist is paced so well. I've been going in circles trying to get started with Tkinter till now. This gave me a confidence boost ! Thank you!

it says that "Lambda is not defined" What Should i do?

Lesson check. Thanks.

nice..

Hey, could anyone please guide me to how to runs these functions(-,+,/,*) with 3 integers, using Tkinter. Thanks!!!

its says invalid syntax for me. That problem came in when there was lambda: button_click(1))
and that problem says the : is the problem

😳Is it "Lambda" ? It looks like "Lambda"!! 🧐 Oh no wait, it is "lambda" with "l" not "L" 😓 what a confusing "text_fönt" 🤣

what does the lambda do??

I like your tutorials but i want to know that how can we make that

First when we start a start button will be visible and when we click it the screen changes to this calculator in that screen only not in another screen
So please tell me

And also
Thank You

I get a syntax error associated with the Lambda; based on some Stack Overflow comments this looks like it's not possible to use in Python 3? I should go try my older version of Python and see if it works there. Not sure how to get around this. OK never mind thanks, I saw your answer about lowercase L in "lambda". But YOUR screen keeps capitalizing them! At least it looks like uppercase.

It would be helpful for us if you write the script in the description too.
But I like your videos.

I request you to please slow speaking because we can't understand what you are saying.
My English is weak .

❤😘😍

I made it better!

Looks nice but how to stylize the calculator?(colors/shapes/etc..)

num1 = input("Type in the first number: ")
num2 = input("Type in the second number: ")
result = float(num1) + float(num2)
print(result)

Please help...

button_1 = Button(root, text="1", padx=30, pady=25, command=Lambda: button_click(1), font=number_font)
^
SyntaxError: invalid syntax

What version of python is everyone using? I'm using 3.9.2 and getting the following error:

button_1 = Button(root, text="1", padx=40, pady=20, command=Lambda: button_click(1))
^
SyntaxError: invalid syntax

I keep rewatching because my calculator window is way bigger that yours. My padx and pady are the same

can you share the code?
