[New-bugs-announce] [issue39387] configparser read_file() with variable

[Mattia Verga]

New submission from Mattia Verga <mattia.verga at gmail.com>:

I'm trying to assign a file object to a variable and then pass this variable to configparse.read_file(), but for some reason that doesn't work:

>>> import configparser
>>> config = configparser.ConfigParser()
>>> config.read_file(open('review-stats.cfg'))
>>> config.sections()
['global']
>>>
>>> config2 = configparser.ConfigParser()
>>> f = open('review-stats.cfg')
>>> f
<_io.TextIOWrapper name='review-stats.cfg' mode='r' encoding='UTF-8'>
>>> config2.read_file(f)
>>> config2.sections()
[]

Shouldn't those results be the same?
