示例1: from_import
# 需要導入模塊: from future.backports import urllib [as 別名]
# 或者: from future.backports.urllib import request [as 別名]
def from_import(module_name, *symbol_names, **kwargs):
"""
Example use:
>>> HTTPConnection = from_import('http.client', 'HTTPConnection')
>>> HTTPServer = from_import('http.server', 'HTTPServer')
>>> urlopen, urlparse = from_import('urllib.request', 'urlopen', 'urlparse')
Equivalent to this on Py3:
>>> from module_name import symbol_names[0], symbol_names[1], ...
and this on Py2:
>>> from future.moves.module_name import symbol_names[0], ...
or:
>>> from future.backports.module_name import symbol_names[0], ...
except that it also handles dotted module names such as ``http.client``.
