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

How to Build A Simple Calculator App with TKinter and Python. In this video we'll start to build a simple calculator app using the stuff we've learned from the previous videos.

In this series I'll show you how to create graphical user interfaces for Python with Tkinter. TKinter comes with Python already, so there's nothing to install!

17:00 if you error syntax you have to replace Lambda to lambda. The syntax is worked than Lambda

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!

Want to see more about making something like this that scales with resizing.

[IceTheCoder]

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

[mrawesome]

I think what helps me learn this is making it my own: changing labels, adding more functions or buttons

[macdonaldjuma]

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

[wrapdoesstuff]

Nice video series and good explanation.

Comment to the commentators: I no sometimes there are weird error messages but I think instead of asking here you could try to figure it out by yourself . It might take some time and can be annoying but at the end of the day you like to learn how to code by yourself and then you'll need to find solutions to upcoming issues.
Cheers

Hello Codemy how can i get an auto selection on a row in a treeview when i get a search
when i search i want to get the result
i try tree.selection_set(), but it can't selected row

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

[abigailhillen-schiller]

Hi John,

Loving your TKinter tutorials so far.

I have a question, though. I wrote this loop to create the buttons for 1-9:

for x in range(1, 4):
y = 10-3*x
for z in range(y, y+3):
btn = Button(root, text=z, padx=40, pady=20,
command=lambda: button_click(z)).grid(row=x, column=z-y)

The buttons are rendered fine, but when I click them, they all insert the number 3 into the entry box, regardless of the number on the button.

Changing the lambda as below solved the problem, but I don't understand why:

lambda q=z: button_click(q)

Can you explain it?

[lukipuki]

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?

You Are Very Good Teacher John Elder Please Make A Video On Doing Webscraping Using Python

[ravinduabeygunasekara]

what are the units of width and height that we define inside the 'root' function? Is it pixels?

[mahmoudmashoun]
