【问题描述】:
python 和 stackoverflow 的新手。 如果我的问题格式不正确,我们深表歉意。
我正在尝试模拟一个用于鱼类保护的应用程序。 如果冬季比目鱼的长度超过 12 英寸,用户应该会收到一条消息将其扔回;如果长度小于或等于 12 英寸,他们可以保留它。
我知道我的错误是

谢谢。

【问题讨论】:
-
您的 github 链接无效。请在此处发布minimal reproducible example,而不是在其他站点。
-
<=条件是正确的,如果你想说没问题。你确定变量是正确的吗? -
Barmar,感谢您的回复。那么,我们不能通过链接发布代码吗?我认为我的 github 设置为私有。将尝试弄清楚如何将其公开。不,我不确定变量是否正确。 . .我从github发布了相关代码。
-
包括您遇到的错误将非常有帮助,例如,我认为在这种情况下,错误可能是
TypeError: string indices must be integers,它可以很好地了解可能出现的问题 -
Tadhg McDonald-Jensen,感谢您的回复。这是错误: if fishLength ['Winter Flounder']
