When invoking Python, you may specify any of these options::
6
python [-bBdEhiOsSuvVWx?] [-c command | -m module-name | script | - ] [args]

The most common use case is, of course, a simple invocation of a script::
8
python myscript.py

Interface options
10
The interpreter interface resembles that of the UNIX shell, but provides some additional methods of invocation:
11
When called with standard input connected to a tty device, it prompts for commands and executes them until an EOF (an end-of-file character, you can produce that with *Ctrl-D* on UNIX or *Ctrl-Z, Enter* on Windows) is read.
12
When called with a file name argument or with a file as standard input, it reads and executes a script from that file.
13
When called with a directory name argument, it reads and executes an appropriately named script from that directory.
14
When called with ``-c command``, it executes the Python statement(s) given as *command*. Here *command* may contain multiple statements separated by newlines. Leading whitespace is significant in Python statements!
