How do I remove spaced before and after commas in a csv file using python?

Question

Currently one row of my csv file looks like this :

314523, 165538, 76255, 335416, 416827 1250536:1 1744638:1 298526:1 1568238:1

I need it to look like this :

314523,165538,76255,335416,416827 1250536:1 1744638:1 298526:1 1568238:1

I only want to remove the spaces after or before commas and leave the other blank spaces as it is.

How can I do this in python?

Note : I am a beginner in python

I would recommend using the replace function. You enter the pattern you want to replace. In your example, the pattern is comma space (', ') and space comma (' ,'). Then say what you want to replace the pattern with (',').

line=line.replace(', ', ',').replace(' ,',',')
