我是 python 新手，我找不到为什么这个程序不起作用？

Question

def snt(a1, b1): 
     snt0 = a1+b1
     return snt0
def mnt(a1, b1): 
     mnt0 = a1*b1
     return mnt0
print("Hello to my console program")
print("This is a basic sum multiplication calculator ")
i=1
while (i>0):
    clicky=input("For sum click on 1 for multiplcation click on 2: ")
    if clicky==1:
        a=int(input("enter a"))
        b=int(input("enter b"))
        f=snt(a,b)   
        print(a ,"+", b ,"=",f)
        input("Click to go out")
        break
   elif clicky==2:
        a=int(input("enter a"))
        b=int(input("enter b"))
        f=mnt(a,b) before
        print(a ,"*", b ,"=", f)
        input("Click to go out")
        break
   else:
        i += 1

I can't understand why it's not working i know something is wrong with the while loop but i can't find it. Note: I"ve just started learning python !

Answer 1

input() returns a string, eg. "1" . you need to cast it to an integer for your comparison to work.

clicky = input(...)
clicky = int(clicky)

Answer 2

Here is the correct Answer:

def snt(a1, b1):
     snt0 = a1+b1
     return snt0
def mnt(a1, b1): 
     mnt0 = a1*b1
     return mnt0
print("Hello to my console program")
print("This is a basic sum multiplication calculator ")
i=1
while (i > 0):
   clicky = input("For sum click on 1 for multiplcation click on 2: ")
   clicky = int(clicky)
   if clicky == 1:
        a = int(input("enter a: "))
        b = int(input("enter b: "))
        f = snt(a,b)   
        print(a ,"+", b ,"=",f)
        input("Click to go out")
        break
   elif clicky == 2:
        a = int(input("enter a: "))
        b = int(input("enter b: "))
        f = mnt(a,b)
        print(a ,"+", b ,"=", f)
        input("Click to go out")
        break
   else:
        i += 1

Answer 3

The input on the variable clicky requires a cast, as you did correctly later for the variables a and b.

def snt(a1, b1):
    snt0 = a1 + b1
    return snt0

def mnt(a1, b1):
    mnt0 = a1 * b1
    return mnt0


print("Hello to my console program")
print("This is a basic sum multiplication calculator ")
i = 1
while (i > 0):
    clicky = int(input("For sum click on 1 for multiplcation click on 2: "))
    if clicky == 1:
        a = int(input("enter a: "))
        b = int(input("enter b: "))
        f = snt(a, b)
        print(a, "+", b, "=", f)
        input("Click to go out")
        break
    elif clicky == 2:
        a = int(input("enter a: "))
        b = int(input("enter b: "))
        f = mnt(a, b)
        print(a, "*", b, "=", f)
        input("Click to go out")
        break
    else:
        i += 1

Next time, when you open a ticket please try to make some effort to clarify what it is not working, what it is the error or the unexpected behavior you get.
