If you invoke the python interpreter from the command line, like this: python and then type in the small program, then "no" you exit the interpreter with a control key (unix and unix-like shells, it is Ctrl-D, don't know in Windows)

If, on the other hand, you put your program in a text file and invoke the python interpreter like this python scriptfilename then the interpreter returns to the shell command line when the script is finished.

Does that answer your question?

Also, if you want to exit from a deeply nested point during the execution you can use

raise SystemExit

or

import sys
sys.exit(0) # use another value, like -1 to mean program failure

raise any error and then don't handle it will quit your program.

But it's best to use sys.exit

Actually, at least in Python 2.6.5, sys.exit() just raises SystemExit http://docs.python.org/library/sys.html#sys.exit

The nice thing about using
raise SystemExit
to exit your program is that you don't have to import anything extra.
