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
Syntax
