Question

I have a dictionary of the example:
E = 527:{ (‘GENERAL MOTORS CORP.’, datetime.date(1, 1, 1), False, ‘KENOSHA’, ‘WI’)}

I need to take out the datetime.date(1,1,1) and turn this into a separate list outside of the tuple. I’m supposed to access the date for multiple keys and include them into a list. I’m very confused and looking to do this for a general for of any key. This is taken from a general data table where the key is index 1 and the values in the tuples are the next indexed values.
Would [E[527][1] be correct?

Answer 1

Use:

dates = [v[1] for k,v in E.iteritems()]

OR:

dates = [v[1] for v in E.itervalues()] 

OR:

from operator import itemgetter

dates = map(itemgetter(1), E.itervalues())

As per you comment it can be something like:

from datetime import datetime

def get_dates(filename, A, B):
    with open(filename) as f:
        dates = [datetime.strptime(row.split()[2], format) for row in f.readlines()]
    dates = [dt for dt in dates if dt.year == A and dt.month == B]
    return [(dt, dates.count(dt)) for dt in set(dates)]
