My tkinter program keeps on freezing/crashing and i'm not sure if it's because of the code-CodePudding

(I'm new to the site so sorry if there are any mistakes)This is the code and i don't know why it keeps crashing i know it is not my PC as many other of my tkinter programs can run on it. I posted all of the code(not very much) because i don't have a clue of the reason. Thanks for any help.

from tkinter import *
Calculator = Tk()
def input0():
 int(input(0))
def input1():
 int(input(1))
def input2():
 int(input(2))
def input3():
 int(input(3))
def input4():
 int(input(4))
def input5():
 int(input(5))
def input6():
 int(input(6))  
def input7():
 int(input(7))
def input8():
 int(input(8))
def input9():
 int(input(9))
def inputplus():
 str(input(" "))
def inputminus():
 str(input("-"))
def inputdivide():
 str(input("/"))
def inputtimes():
 str(input("*"))
def inputdecimal():
 str(input("."))
def equal():
    eval

CodePudding user response：

Things are wrong: when you input, you get the text passed by user, and leave it. in equal(), eval function has no parameters.

the fixed code:

work = ''

from tkinter import *

Calculator = Tk()


def input0():
    global work
    # int(input(0))
    work = work   '0'

def input1():
    global work
    # int(input(1))
    work = work   '1'


def input2():
    global work
    # int(input(2))
    work = work   '2'


def input3():
    global work
    # int(input(3))
    work = work   '3'


def input4():

    work = work   '5'


def input6():
    global work
    # int(input(6))
    work = work   '6'


def input7():
    global work
    # int(input(7))
    work = work   '7'


def input8():
    global work
    # int(input(8))
    work = work   '8'


def input9():
    global work
    # int(input(9))
    work = work   '9'

    global work
    # str(input(" "))
    work = work   ' '


def inputminus():
    global work
    # str(input("-"))
    work = work   '-'

Calculator.mainloop()

Now it will print the result when you click "=" button. There is no input needed because you give the value by clicking button
