Python: Split, strip, and join in one line

Question

I'm curious if their is some python magic I may not know to accomplish a bit of frivolity

given the line:

csvData.append(','.join([line.split(":").strip() for x in L]))

I'm attempting to split a line on :, trim whitespace around it, and join on ,

problem is, since the array is returned from line.split(":"), the

for x in L #<== L doesn't exist!

causes issues since I have no name for the array returned by line.split(":")

So I'm curious if there is a sexy piece of syntax I could use to accomplish this in one shot?

Cheers!

Answer 1

>>> line = 'a: b :c:d:e  :f:gh   '
>>> ','.join(x.strip() for x in line.split(':'))
'a,b,c,d,e,f,gh'

You can also do this:

>>> line.replace(':',',').replace(' ','')
'a,b,c,d,e,f,gh'
