python解析错误时发生意外的EOF

问题描述

swim_length =int(input("Please enter a swim length: "))

while swim_length < 0:
print("The length has to be a positive number")
swim_length=int(input("Please enter a positive number: ")

您好，有人可以帮我吗，我确定我犯了一个简单的错误，但我不知道确切的位置。

解决方法

您必须在while循环中添加缩进，并在最后一行的末尾添加括号：

swim_length =int(input("Please enter a swim length: "))

while swim_length < 0:
    print("The length has to be a positive number")
    swim_length=int(input("Please enter a positive number: "))

,

在最后一行的第一行中，您错过了结尾）

swim_length=int(input("Please enter a positive number: "))

while循环的主体也需要缩进

while swim_length < 0:
    print("The length has to be a positive number")
    swim_length=int(input("Please enter a positive number: ")
