Boilerplate regular expression parser for python

# file to write to

# traverse the file
for line in infile:

        ''' 
        at this point, our match is in our target var
        this is the perfect spot to massage our data
        by either snipping, appending, prepending or
        whatever
        '''
        print(target) # print values caught
        outfile.write(target+"\n") # write them to file
        
# close both files
outfile.close()
infile.close()
