Shebang
You can call any python as a regular executable script if you add this line to the top of the file:
#!/usr/bin/env python
Get command-line arguments
This is my-script:
#!/usr/bin/env python
import sys
# the first argument is the script name itself
print('This script was passed', len(sys.argv)-1, 'arguments.')
print('Arguments:', sys.argv[1:])
print('Argument 1 is: ', sys.argv[1])
Sample call/output
$ ./my-script foo bar
This script was passed 2 arguments.
Arguments: ['foo', 'bar']
Argument 1 is: foo
