Off the top of my head, something like re.sub(', *', ', ', 'a,
b,c,d,e, f'), meets your requirements (it also ensures the number of
spaces after the comma is one). However, you may need to refine the
rules depending on what you really want to achieve. For instance, what
happens with: a comma appearing before any text, consecutive commas (ie
,,,), or commas within quotes?
