python - I am trying to process a file passed as a command line argument -

i trying process file passed command line argument. right there 1 argument, plan add others.

here code far:

import argparse  parser = argparse.argumentparser(description="sample arg parsing")  parser.add_argument('-f',type=file)  try:     print parser.parse_args() except ioerror, msg:     parser.error(str(msg)) 

i can't figure out how pass argument file handle open , process. , yes, n00b. try block there testing.

you need pass filename string. then, can use open() open file filename. refer python docs here (7.2 - reading & writing files).
