問題是問號在 Python 中不是有效字符。
In Python, the % operator can be used to get the remainder of a division operation. For example, if you divide 7 by 3, the remainder is 1. So 7 % 3 is 1. If you have a string that contains a question mark (?), you can use the % operator to get the question mark out of the string. For example, "abc?def" % 2 is "def".
