if (len(sys.argv) > 1):         


        

Answer 1

It can be useful to catch the exception an print the offending lines

for line in f:
    line = line.strip("\n ' '")
    line = line.split(",") 
    try:
        print line[1]
    except IndexError, e:
        print e
        print "line =", line
        raise   # if you don't wish to continue
