python - Write multiple matches from regex to a file on a single line a certain way -

i trying write multiple matches regex file on single line way.

matches = re.findall(<form>(.*?)</form>, line, re.dotall) form in matches:   form = ("'" + form + "', ")   f = open(new_file, 'a+')     f.write(form.rstrip('\n'), ) 

the above gives me this:

'form1', 'form2',....,'formn', 

how can have them enclosed in parentheses , no comma @ end below?

('form1', 'form2',....,'formn') 

thanks much.

something this?

matches = re.findall(<form>(.*?)</form>, line, re.dotall) if matches:     f = open(new_file, 'a+')       f.write("('%s')" % "', '".join(matches))     f.close()
