How to get a list of months using python

.. dirty dirty dirty... ;D

[Python] [Hacks] [Django]

This is a quick-and-dirty hack that came to my mind this morning. I needed a list where each element is a tuple containing (month number, month name). This little snippet will do the trick:

months_choices = []
for i in range(1,13):
    months_choices.append((i, datetime.date(2008, i, 1).strftime('%B')))

The result will be something like:

>>> months_choices = []
>>> for i in range(1,13):
...     months_choices.append((i, datetime.date(2008, i, 1).strftime('%B')))
...
>>> months_choices
[(1, 'January'), (2, 'February'), (3, 'March'), (4, 'April'), (5, 'May'), (6, 'June'), (7, 'July'), (8, 'August'), (9, 'September'), (10, 'October'), (11, 'November'), (12, 'December')]
>>>

The name of the month will be translated to you locale configuration (according to python documentation, you can take a look there to replace that with, for example, the abbreviated name). This is a perfect list to be used as the default list of options with a django ChoiceField or MultipleChoiceField form field ;D.

Re: How to get a list of months using python

look at calendar.month_name :)
It's much simplier )

Re: How to get a list of months using python

Thnx for the tip Maxim. I didn't know about calendar.month_name.

In my example we could switch:



datetime.date(2008, i, 1).strftime('%B')

to:



calendar.month_name[i]

which is even cleaner. Thnx!

Re: How to get a list of months using python

now = datetime.datetime.now()

calendar.month_name[now.month]

Re: How to get a list of months using python

I used your code from this and turned it into a list comprehension:

import datetime
months = [datetime.date(2000, m, 1).strftime('%m - %B') for m in range(1, 13)]

Guys, try this

from django.utils.dates import MONTHS

Re: How to get a list of months using python

@skoval: sure, thanks for the hint!

OTOH: I wonder if django has that util back in 2009, when this post was written... :P

Re: How to get a list of months using python

You can also directly iterate over calendar.month_name like this:

import calendar
for month in calendar.month_name[1:]:
print(month)

I use slice cos first element of this iterable is empty string.

Re: How to get a list of months using python

thanks to Nosterx:
months = dict(enumerate((name for name in calendar.month_name if name), start=1))
