.replace()如果它们始终出现在字符串方法中，或者.strip()仅在开始和/或结束时出现，则只需使用它们：
a = '"sajdkasjdsak" "asdasdasds"'
a = a.replace('"', '')
'sajdkasjdsak asdasdasds'
# or, if they only occur at start and end...
a = a.strip('\"')
'sajdkasjdsak" "asdasdasds'
# or, if they only occur at start...
a = a.lstrip('\"')
# or, if they only occur at end...
a = a.rstrip('\"')
