Command-line arguments in Python show up in sys.argv as a list of strings (so you'll need to import the sys module).

For example, if you want to print all passed command-line arguments:

import sys
print(sys.argv)  # Note the first argument is always the script filename.

Command-line options are sometimes passed by position (e.g. myprogram foo bar) and sometimes by using a "-name value" pair (e.g. myprogram -a foo -b bar).
