在第32行，我得到以下错误：
charsettest = re.findall(ur"name=\"charset_test\" value=\"([^\"]*)",curlData)
是无效的语法。我看不出有什么问题，并且语法错误是。有人可以帮我这行的语法吗？在此先感谢您的帮助，我真的很感激！
只需删除u此ur"regex"声明中的内容即可。
charsettest = re.findall(r"name=\"charset_test\" value=\"([^\"]*)",curlData)
您可以按顺序在单引号中编写上述正则表达式，以避免转义双引号。
charsettest = re.findall(r'name="charset_test" value="([^"]*)"',curlData)
例子：
>>> s = '345foo56'
>>> re.findall(r'\d+', s)
['345', '56']
>>> re.findall(ur'\d+', s)
SyntaxError: invalid syntax
>>>
