[新手 Python 疑问贴] 这个为什么老提示我语法错误了呢？

This topic created in 3672 days ago, the information mentioned may be changed or developed.

感谢各位点进来，非常感谢！问题如下：

def Ackermann(m, n):
    if m == 0:
        return n + 1
    elif m > 0 and n == 0:
        return Ackermann(m-1, 1)
    elif m > 0 and n > 0:
        return Ackermann(Ackermann(m-1, Ackermann(m, n-1))
    else:
        return('not definition')

Ackermann(int(input('enter your m:')), int(input('enter your n:')))

D:\--->python HelloWorld.py
  File "HelloWorld.py", line 9
    else:
       ^
SyntaxError: invalid syntax

这里面还有一个错误，我把 else 这行注释以后，还是提示我语法错误：

D:\--->python HelloWorld.py
  File "HelloWorld.py", line 12
    Ackermann(int(input('enter your m:')), int(input('enter your n:')))
            ^
SyntaxError: invalid syntax
