my python repl is using sys.argv, how do I pass one in order to test ?
Press Ctrl-Shift-P inside your repl and then "Open Shell".
This will open a normal shell inside your repl directory, where you can run your program as you would on a regular command prompt, with command line arguments.
There might be a better way to do this, but this is the only way I know.
Sorry for the late reply, and keep coding on repl.it!
