God bless you! Om namah shivay jay mahakal bless uou

[bharatgoyal]

Thanks a lot Harry. Your tutorials were really amazing. I just want to add something in this tutorial. Instead of changing padding of each button, we can increase the width of each button and set it to constant say, width =4. Then, we wont need to manually check padding. GUI will become well structured in no time.

[saptakmukherjee]

Hey Harry! Here's my best attempt of reducing the amount of code. I managed to reduce it by half [65 lines]...(I tried my best to reduce the lines while maintaining design and uniformity, so there might be repetitions, and it might not be the best way.) Here's the code:

from tkinter import *
root = Tk()
root.geometry("620x888")
root.title("Calculator")

def click(event):
global svalue
text = event.widget.cget("text")

if text == "=":
if svalue.get().isdigit():
value = int(svalue.get())
else:
try:
value = eval(svalue.get())
except Exception as e:
print(e)
value= "Error"

svalue.set(value)
screen.update()

elif text == "C":
svalue.set("")
screen.update()
else:
svalue.set(svalue.get() + text)
screen.update()

while x<=7:
f = Frame(root, bg="grey")

short key key is ctrl + mouse scroll, but first you need to enable this in setting in pycharm ->

first open pycharm -> press crl+alt+s(settings) -> editor settings -> general > tick the first option(you will see a option saying "change font size with mouse scull wheel")
