Here is the value i got from API server
{"query":{"pages":{"-1":{"ns":0,"title":"spencerx","missing":""}}}}
Let say if i want to get determine if it's not missing word, i will know by looking at "-1" of the return. but when the word exist, it will returning me the following json
{"query":{"pages":{"1080152":{"pageid":1080152,"ns":0,"title":"spencer"}}}}
which is a random number. may i know how could i detect that's '-1' and determine the word doesn't exist? while i try to print x['query']['pages'] it will just throw all the following behind to me, but i don't know how to detect it's key error. thanks.
try print x['query']['pages'].keys(), which would give you ['-1'] for the first case and ['1080152'] for the second one.
if you just want to check '-1' in x['query']['pages']:
if '-1' in x['query']['pages']:
# dictionary x['query']['pages'] has '-1' as a key
would suffice
