Python 程序没有运行

我正在尝试运行一个代码，但它不起作用，如果有错误，我似乎找不到

def question3():
x= input("Enter the first value:")
y= input("Enter the second value:")
z= input("Enter the third value:")
if x==y==z:
    print("All three inputs have equal values" + x)
elif x==y:
    print("x and y have equal values" + x)
elif x==z:
    print("x and z have equal values" + x)
elif y==z:
     print("y and z have equal values" + y)
else:
    print("All three inputs have different values")

你调用函数question3吗？如果有正确的标识，它会为我运行。你们使用Python3吗？格式是错的，缩进了。因为您没有指定您将遇到的错误，所以这大概就是您要问的问题。

def question3():
    x= input("Enter the first value:")
    y= input("Enter the second value:")
    z= input("Enter the third value:")
    if x==y==z:
        print("All three inputs have equal values" + x)
    elif x==y:
        print("x and y have equal values" + x)
    elif x==z:
        print("x and z have equal values" + x)
    elif y==z:
         print("y and z have equal values" + y)
    else:
        print("All three inputs have different values")
    return
