Python Interpreter

We can start the Python interpreter from the command line.

Change to the directory where the interpreter lives, or add

the directory to your path. Then type

python

On UNIX, Python typically lives in /usr/local/bin; on Windows, Python probably lives in c:\python20.

On Windows, you can also bring the interpreter up from Start ➪ Programs ➪ Python 2.0 ➪ Python (command line).

Once we start the interpreter, Python displays something like this:

Python 2.0 (#8, Oct 1 2011, 17:27:58) [MSC 32 bit (Intel)] on win32

Type “copyright”, “credits” or “license” for more information.

>>> 

The interpreter displays the >>> prompt to show that it’s ready for you to type in

some Python. And so, in the grand tradition of programming books everywhere, we

proceed to the “Hello world” example:

>>> print “Hello world!”

Hello world!

To exit the interpreter, type the end-of-file character (Ctrl-Z on Windows, or Ctrl-D on Linux) and press Enter.
