Decoding nested JSON with multiple 'for' loops

Question

I\'m new to Python (last week), and have reached my limit. Spent three days on this, most of my time in stackoverflow, but I cannot work out how to go any further!

First of all, don't use an index but loop directly over the lists; that way you can give them meaningful names. The top-level is a list of entries, each entry is a dictionary with a 'innings' key, and each innings is a list of dictionaries, with, among others, a wickets key:

for entry in data:
    for inning in entry['innings']:
        print inning['wickets']

This prints:

>>> for entry in data:
...     for inning in entry['innings']:
...         print inning['wickets']
... 
10
9
0
0

This makes it easier to add information at each level too:

>>> for entry in data:
...     print entry['description']
...     for i, inning in enumerate(entry['innings']):
...         print 'Innings {}: {} wickets'.format(i + 1, inning['wickets'])
...
