datetime module question

[deanhystad]

There are a lot of errors.

&Y is not a datetime format code.
mkdir {0}" is missing a starting "

The imports are all messed up:

rom datetime import datetime, date

oneday = datetime.timedelta(days-1)
yesterday = datetime.date.today() - oneday

datetime.timedelta(days-1) was probably meant to be datetime.timedelta(days=1)

You should not use \ as separators in a datetime format string. Use / or \\.
