Splitting by ',' in a dictionary while retaining the lists inside

Question

I've been looking for a way to split by ',' in a dictionary while retaining the present lists but have not been succesful. I want to split this dictionary:

{'R_ARABR': ['YHR104W'], 'R_GLYCt': ['YLL043W'], 'R_LPP_SC': ['YDR284C', 'YDR503C'], 'R_TREH': ['YDR001C', 'YBR001C'], 'R_CTPS2': ['YBL039C', 'YJR103W'], 'R_CTPS1': ['YBL039C', 'YJR103W']}

To appear like this:

{'R_ARABR': ['YHR104W'],
'R_GLYCt': ['YLL043W'],
'R_LPP_SC': ['YDR284C', 'YDR503C'],
'R_TREH': ['YDR001C', 'YBR001C'],
'R_CTPS2': ['YBL039C', 'YJR103W'],
'R_CTPS1': ['YBL039C', 'YJR103W']}

Help is much appreciated!

What are you splitting? You have a dict with lists and you seem to want the same output as you already have — Padraic Cunningham, Jun 10 '16 at 10:36
It seems you just want to pretty print the dictionary? Is it so? — Vikas Ojha, Jun 10 '16 at 10:37

You can use pprint.pprint, eg:

>>> import pprint
>>> d = {'R_ARABR': ['YHR104W'], 'R_GLYCt': ['YLL043W'], 'R_LPP_SC': ['YDR284C', 'YDR503C'], 'R_TREH': ['YDR001C', 'YBR001C'], 'R_CTPS2': ['YBL039C', 'YJR103W'], 'R_CTPS1': ['YBL039C', 'YJR103W']}
>>> pprint.pprint(d)
{'R_ARABR': ['YHR104W'],
 'R_CTPS1': ['YBL039C', 'YJR103W'],
 'R_CTPS2': ['YBL039C', 'YJR103W'],
 'R_GLYCt': ['YLL043W'],
 'R_LPP_SC': ['YDR284C', 'YDR503C'],
 'R_TREH': ['YDR001C', 'YBR001C']}

If you want to get the result as a string to then use elsewhere (maybe write to a file), then use pprint.pformat as pprint.pprint writes directly to stdout and returns None.

This indeed works in the console. I want to write it to a .txt file. Unfortunately, it writes 'none'. Any thoughts? – Cheeseburgler Jun 10 '16 at 11:33
