python - How to change date format of a date inside a string? -


this question has answer here:

i have string "hello please change date 04/24/2017 putting month in middle"

class paragraph:      @staticmethod     def change_date_format(paragraph):         return none  print(paragraph.change_date_format('hello please change date 04-24-2017 putting month in middle'))

i need change "hello please change date 24/04/2017 putting month in middle"

import re def change_date_format(paragraph):     return re.sub('(\d+)/(\d+)/(\d+)',          lambda m: '{}/{}/{}'.format(m.group(2), m.group(1), m.group(3)),          paragraph)

this finds sequence of 3 groups of digits separated slashes (like 04/27/2017), uses format swap first , second group.
