Hey,
I'm working on a problem out of Core Python Programming (2nd Edition).
Basically, I'm creating a class that formats dates. Here is what I have so
far:
Consider reformatting the month_dict so each name and abbreviation is a key.
Then you can just look up the potential key rather than looping thru all the
keys. That is what dictionaries are for!:
month_dict = {"jan" : 1,
"january" : 1,
"feb" : 2,
"february" :2, etc ...}
...
except ValueError:
if month.lower() in month_dict:
month = month_dict[month.lower()]
else:
month = ""
The dict function is also handy here:
month_dict = dict(
jan = 1,
january = 1,
feb = 2,
february = 2, etc ...)
Dear Christopher,
Instead of multiplying the keys for each possible version of the written
month, I would rather have:
month_dict = {"jan":1,
"feb":2, ...}
and have:
written_month = written_month[:3].lower()
if written_month in month_dict:
# do something
Regards,
Benoit.
