python - Pep8 E501 : line too long error

Question

我从这段代码中得到错误 E501: line too long:

header, response = client.request('https://api.twitter.com/1.1/statuses   /user_timeline.json?include_entities=true&screen_name='+username+'&count=1')

但如果我这样写或另一种方式:

    header, response = client.request('\
       https://api.twitter.com/1.1/statuses/user_timeline.\
           json?include_entities=true&screen_name='+username+'&count=1')

我收到这个错误:

ValueError: Unsupported URL             https://api.twitter.com/1.1/statuses/user_timeline            .json?include_entities=true&screen_name=username&count=1 ().

或者我得到这个错误:

ValueError: No JSON object could be decoded

所以请告诉我，我怎样才能通过这个错误？

Answer 1

如果您这样打断行首的空格，它们将成为您的字符串的一部分。

试试这个:

header, response = client.request(
   'https://api.twitter.com/1.1/statuses/user_timeline.'
   'json?include_entities=true&screen_name=' + username + '&count=1')

字符串将为 automatically be concatenated .
