Let's say I have a python script myscript.py, which takes multiple named arguments. The user calls the script as python myscript.py --arg1 value1 --arg2 value2. How to capture this whole command (i.e. python myscript.py --arg1 value1 --arg2 value2 ) and save it to a text file "command.selfie" using the same script that the user is calling?

sys.argv is a list with all the arguments. This will help:
import sys
command = " ".join(sys.argv)
# do whatever you want to do with command: str

You can do something like this:
import argparse
import sys
def main(argv):
parser = argparse.ArgumentParser()
parser.add_argument("--arg1", default=False, help="Explain arg1")
parser.add_argument("--arg2", type=str, default="hello", help="Explain arg2")
# add all arguments you need
args = parser.parse_args(argv[1:])
params = {"arg1": args.arg1,
"arg2": args.arg2, }
print(params["arg1"])
print(params["arg2"])
if __name__ == "__main__":
sys.exit(main(sys.argv))
