You could use the argparse module that python provides: argparse tutorial

Then you would write the following:

python myscript.py arg1 arg2 arg3

if python file is your own:

1) Add this to the first line of your python file:

 #!/usr/bin/python

2) in shell make file executable:

chmod +x your_python_file.py

3) exec like a compiled program or bash script:

./your_python_file.py param1 param2 param3

use a here-doc:

python myscript.py <<EOF
input line 1
input line 2
input line 3
EOF
