我写了一个代码来分隔偶数和奇数，但我遇到了这个错误？

while True:
    num = input("pls type the number: ")
    
    # check if it's int or string 
    
    number = int(num)  
    except ValueError:
    print("error try again !!")
    continue  # if it was wrong go back
    
    # check if it's even or odd
    if number % 2 == 0:
        result = number * 2
        print("it's even" , number)
        print("The End")
    else:
        result = number + 1
        print("its odd",number)
        print("The End")
    break 

SyntaxError: invalid syntax

怎么了 ？

你的 try...except 块的缩进有误。 except ValueError: 行需要与 number = int(num) 行缩进一致。

以下是已更正的代码：

while True:
    num = input("pls type the number: ")

    # 检查是否是整数或字符串
    try:
        number = int(num)  
    except ValueError:
        print("error try again !!")
        continue  # 如果错误则返回

    # 检查是偶数还是奇数
    if number % 2 == 0:
        result = number * 2
        print("it's even" , number)
        print("The End")
    else:
        result = number + 1
        print("its odd",number)
        print("The End")
    break 

此更正确保了 except ValueError: 块与 try 块正确关联，从而解决了语法错误。
