python - Strptime Weeks Error -

i'm writing scripts require manipulating week of year is. inputs in form yyyyww, such '201435'.

during attempts use strptime it, reason, defaults first of year. example:

import datetime test = '201435' test = datetime.datetime.strptime(test,'%y%u') print(test)

outputs

2014-01-01 00:00:00

i'm not sure why it's doing so. using time module or replacing %u %w has exact same result.

when used strptime() method, %u , %w used in calculations when day of week , year specified.

therefore, don't specify day in week, week number ignored , first of year. fix that, add day:

>>> datetime.datetime.strptime('2014350', '%y%u%w')                                     # ^ here   ^ , here datetime.datetime(2014, 8, 31, 0, 0)
