我是python新手，我不知道为什么这个程序不工作？

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

我不明白为什么它不工作，我知道有些东西是错误的，而循环，但我找不到它。 注意：我刚刚开始学习python

Answer 1

input()返回字符串，例如"1"。您需要将其转换为整数，以便比较工作

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

Answer 2

变量clicky的输入需要一个cast，正如您稍后对变量a和b所做的那样

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

下一次，当你打开一张罚单时，请试着弄清楚什么是不起作用的，什么是错误或者你得到的意外行为

Answer 3

以下是正确答案：

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
