python - Imgur API: Dictionary values magically turns into None? -


i know voodoo magic isn't cause of - sure seems it!

i have following code snippets, making use of imgur api. imgur object client imgur api uses , contains attribute credits displays number of access credits user has on website.

imgur = imgurpython.imgurclient(client_id, client_secret)

calling:

imgur.credits

returns credits normal, i.e.:

{'clientlimit': 12500, 'userreset': 1503185179, 'userlimit': 500, 'userremaining': 0, 'clientremaining': 12000}

however when attempt call dictionary in later function:

def check_credits(imgur):     '''         receives client - , if there not credits left,         wait until credit refills - i.e. pause program     '''     credits = imgur.credits     credits_remaining = credits['userremaining']     reset_time = credits['userreset']      if credits_remaining < 10:         print('not enough credits, remaining: %i' % credits_remaining)         = int(dt.utcnow().timestamp())         wait_time = reset_time -         print('waiting for: %i' % wait_time)         time.sleep(wait_time)

sometimes values in dictionaries seem turn none instead of integers supposed be. in case both reset_time , credits_remaining turn out none. in order allow code run i'm having add try-catches on code , it's getting quite frustrating. way, function called whenever error imgurclientratelimiterror, when imgur.credits['userremaining'] == 0. i'm wondering if know why may have been case.

upon looking @ source code client seems updated automatically upon each request. updated values obtained response headers after call imgurclient.make_request. header values obtained dict.get can return none if key not exist in headers dictionary. code reference here: https://github.com/imgur/imgurpython/blob/master/imgurpython/client.py#l143

i not sure if these headers still used on errors 404 or 403 investigate further there. seems though because of behavior need either cache previous values or manually call imgurclient.get_credits method in these cases real values. whichever fix go you.
