Print results of re.search as a CSV string

Question

I'm writing a script to parse out lines of interest from a log. It is working well except for printing the lines. I have a parameterized regex that I use in an re.search, which returns my results. I can print them individually or by looping through the list.

My problem is that for each match, I want to print a CSV line, basically each value in quotes with a comma between (and no comma on the end of the line). Is there an easy way to do this?

I have this:

   if lineMatch:
      for capturedToken in lineMatch.groups():
        #print capturedToken

Using Python 2.7 how would I print as a CSV line (followed by a new line)?

I've tried print/end but from what I understand that is only Python 3.x - every variation I tried gave me syntax errors. I'm sure there's a cool Pythonic way to print the values from the linematch group as a comma separated list; I just don't seem to be able to find it!

Answer 1

I think you want this:

if lineMatch:
    print(', '.join(['"{}"'.format(t) for t in lineMatch.groups()]))

Usage:

>>> m = re.search('(\d{4})-(\S+)', "1995-jun")
>>> print ', '.join(['"{}"'.format(i) for i in m.groups()])
"1995", "jun"

Answer 2

Use join method from strings like this:

print ",".join(lineMatch.groups())
