/**
   Solution to the 'Substring Sum' problem:
   Accept a string consisting of digits and return the number of possible groupings of digits such that
   sum of digits of each grouping at the left is less than or equal to sum of digits of every grouping on the right (i.e. they are in ascending order).
   For example:
   String = "1337"
   Groupings: "1,337"; "1,3,37"; "1,3,3,7"; "1,33,7"; "13,37"; "13,3,7"; "133,7"

def create_directories(basepath, start_date, end_date, date_format='%Y%m%d'):
	""" Creates all subdirectories under the specified path named after the specified dates, one for each date.

	start_date and end_date are both datetime.date objects.
	date_format is a format string for the date which will be used to name the directories.

	Example:
	create_directories('/home/myhome', date(2016, 01, 01), date(2016, 01, 03)) will create directories named 20160101, 20160102 and 20160103 within /home/myhome.
	Directory structure is created recursively if it doesn't exist.
