The params keyword takes a dictionary representing query parameters; if you give a key a list of values, then each of those values is represented as a separate entry in the query string. The [] suffix on names is a PHP / Ruby-on-Rails convention, you'll need to supply it yourself:

params = {'path[]': ['/empty', '/Burns.docx', '/Byron.doc']}
headers = {'Some-header', 'Header value'}
response = requests.get(url, params=params, headers=headers)

Here the path[] parameter is given a list of values, each becomes a separate path[]=<value> entry in the query string.

Demo:

>>> import requests
>>> params = {'path[]': ['/empty', '/Burns.docx', '/Byron.doc']}
>>> url = 'http://httpbin.org/get'
>>> response = requests.get(url, params=params)
>>> response.url
u'http://httpbin.org/get?path%5B%5D=%2Fempty&path%5B%5D=%2FBurns.docx&path%5B%5D=%2FByron.doc'
>>> from pprint import pprint
>>> pprint(response.json())
{u'args': {u'path[]': [u'/empty', u'/Burns.docx', u'/Byron.doc']},
 u'headers': {u'Accept': u'*/*',
 u'Accept-Encoding': u'gzip, deflate, compress',
