Parsing arguments while running script with IPython

Question

I often run scripts with ipython -i or ipython --pdb. I would like to make a script which parses arguments without interfering with being run in this manner. I've attempted to do this below in the file ipy_parse.py:

import argparse
parser = argparse.ArgumentParser()
parser.add_argument(
 '-lf', '--proglogfile',
 help="File for logging",
 dest="plogfile",
 type=str
)
args = parser.parse_args()
print(args.plogfile)

However, when I run this with ipython ipy_parse.py --proglogfile="wat", I get the following output:

[TerminalIPythonApp] WARNING | Unrecognized alias: '--proglogfile=wat', it will probably have no effect.
None

Despite the fact that this script works normally when run with python ipy_parse.py --proglogfile="wat". How can I parse arguments without interfering with IPython arguments?

Answer 1

You can separate ipython arguments from your script arguments using --:

ipython ipy_parse.py -- --proglogfile="wat"
