>>> a = 'chengyucdntest.okeygame.com_2023090613_5_120.log.gz'
>>> a.strip('.gz')
'chengyucdntest.okeygame.com_2023090613_5_120.lo'
>>> b = 'E384UD843W7GXZ.2023-09-06-09.fce6535e.gz'
>>> b.strip('.gz')
'E384UD843W7GXZ.2023-09-06-09.fce6535e'
如上， 有点无法理解为什么 a.strip('.gz')的值后边会少一个 g
有没有大佬解释一下的？

strip('.gz')的意思是去除. g z 三个字符中的任意一个，当年我初学 python 就踩过这坑。
你的目的可以用 removeSuffix |

Python 文档是这么解释的。
Return a copy of the string with the leading and trailing characters removed. The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped. a.strip('gz.')会得到一样的结果，strip 的参数仅表示从开头或结尾移除的字符集 |

可以试试 print(a.replace('.gz', ''))。
