您可以通过使用解析Python代码来删除注释
tokenize.generate_tokens。以下是从docs对该示例进行的稍微修改的版本：
import tokenizeimport ioimport sysif sys.version_info[0] == 3: StringIO = io.StringIOelse: StringIO = io.BytesIOdef nocomment(s): result = [] g = tokenize.generate_tokens(StringIO(s).readline) for toknum, tokval, _, _, _ in g: # print(toknum,tokval) if toknum != tokenize.COMMENT: result.append((toknum, tokval)) return tokenize.untokenize(result)with open('script.py','r') as f: content=f.read()print(nocomment(content))例如：
如果script.py包含
def foo(): # Remove this comment ''' But do not remove this #1 docstring ''' # Another comment pass
然后的输出
nocomment是
def foo (): ''' But do not remove this #1 docstring ''' pass
