You can use the split function in Python to easily create a comma delimited set. If you have a divider to split upon, a script can substitute that divider with quotation marks and commas.

Follow these steps:

1. Name the set with the text you need to divide up.

>>> set1 = 'manchester england bristol england london england'

2. Use the split function with the divider designated in parentheses: >>> set1.split("england")

3. It will generate a nice comma delimited set. ['manchester ', ' bristol ', ' london ', ''] >>>
