在Python中，如何以交互方式提供命令行参数

Question

I am new to Python. I want to run a software in interactive mode. In the manual it says the usage

python experiment.py --config config.yaml --out result/

The question is, how can I supply the command line arguments to experiment.py in interactive mode?

Answer 1

The commandline arguments that eg optparse and argparse uses are taken by default from sys.argv element 1 and up. You can always do:

import sys
sys.argv[1:] = ['--config', 'config.yaml', '--out', 'result/']

Although eg in argparse you can provide the arguments explicitly to .parse_args() as well and then that method will not inspect sys.argv

Answer 2

If I understood you correctly you need something like this:

while True:
    query = raw_input("> ")
    if query == "exit":
        break
    # do something useful
