我的代码不起作用，我该如何解决？

Question

Basicly I just made a Calculator Code (it should probably work) but is just shows the Ascii Art CALC but doesn't actually run the Calculator Code, no error or anything, just doesn't run a Part of Code for some Reason. -_- (The Ascii Art in the Code may look messy but actually its ok in the cmd)

You never call your functions. They don't automatically run if they don't get called. So you can call it like yourfuncname() .

import time
from colorama import init, Fore
init()

print(Fore.CYAN)
print("  _______     ____     ___          _______")
print(" /       |   /    \\   |   |        /       |")
print("|    ____/  /  /\\  \\  |   |       |    ____/")
print("|   |      |  /  \\  | |   |       |   |")
print("|   |      |  ¯¯¯¯  | |   |       |   |")
print("|   |      |   __   | |   |       |   |")
print("|    ¯¯¯¯\\ |  |  |  | |   ¯¯¯¯¯¯\\ |    ¯¯¯¯\\")
print(" \\       | |  |  |  | |         |  \\       | U L A T O R  //made by dot.")
print("  ¯¯¯¯¯¯¯   ¯¯    ¯¯   ¯¯¯¯¯¯¯¯¯    ¯¯¯¯¯¯¯")
print(Fore.WHITE)

def start():
    func = input("\n+ - * / : ")
    p = input("Math Problem: ")
    pl_ps = p.split(" + ")
    mi_ps = p.split(" - ")
    mu_ps = p.split(" * ")
    di_ps = p.split(" / ")
    if func == "+":
        one = int(pl_ps[0])
        two = int(pl_ps[1])
        answer = one + two
        print(answer)
    elif func == "-":
        one = int(mi_ps[0])
        two = int(mi_ps[1])
        answer = one - two
        print(answer)
    elif func == "\*":
        one = int(mu_ps[0])
        two = int(mu_ps[1])
        answer = one * two
        print(answer)
    else:
        if func == "/":
            one = int(di_ps[0])

    exit = input("Restart(r),Exit(e): ")
    if exit == "r":
        start()
    else:
        if exit == "e":
            print("Closing Programm...")
            time.sleep(1)
        else:
            print("The option " + '"'+exit+'"' + " does not exist.")
            time.sleep(1)
            e()

Answer 2

how are you running your script? Is it being called by another script or are you running this script directly? If the latter, you never called start()
