Python's requests mess

1. Pre-configured

Session () ss.headers.update ({'user-agent':'mozilla/5.0 (Windows NT 6.1; WOW64; rv:54.0) gecko/20100101 firefox/54.0'})#C:\Program files\anaconda2\lib\site-packages\urllib3\connectionpool.py:858:insecurerequestwarning:#unverified HTTPS request is being made.

Sending JSON in Requests

3. Using Retries in Requests

Retries in Requests

(1) Simple rough

S.mount ('https://', Httpadapter (max_retries=5))

(2) Finer grain size

 from  requests.packages.urllib3.util import   Retry  from  requests.adapters import   Httpadapter  from  requests import   Sessions  = Session () S.mount ( "  https://pypi.python.org/  "  =retry (total=5, status_forcelist=[500, 503 = S.get ( " https:// pypi.python.org/simple/requests/  ")
