Unless you use some sort of integrated development environment, you will end up
*typing* Windows commands into what is variously referred to as a "DOS window"

Start menu; under Windows 7 the menu selection is :menuselection:`Start -->
Programs --> Accessories --> Command Prompt`. You should be able to recognize

First, you need to make sure that your command window recognises the word
"python" as an instruction to start the interpreter. If you have opened a
command window, you should try entering the command ``python`` and hitting
"py" as an instruction to start the interpreter. If you have opened a
command window, you should try entering the command ``py`` and hitting
return:

.. code-block:: doscon

C:\Users\YourName> py

If the ``python`` command, instead of displaying the interpreter prompt ``>>>``,
gives you a message like::
Now that we know the ``py`` command is recognized, you can give your
Python script to it. You'll have to give either an absolute or a
relative path to the Python script. Let's say your Python script is
located in your desktop and is named ``hello.py``, and your command
prompt is nicely opened in your home directory so you're seeing something
similar to::

'python' is not recognized as an internal or external command, operable program or batch file.
C:\Users\YourName>

or::
So now you'll ask the ``py`` command to give your script to Python by
typing ``py`` followed by your script path::

Bad command or filename

then you need to make sure that your computer knows where to find the Python
interpreter. To do this you will have to modify a setting called PATH, which is
a list of directories where Windows will look for programs.

You should arrange for Python's installation directory to be added to the PATH
of every command window as it starts. If you installed Python fairly recently
then the command ::

dir C:\py*

will probably tell you where it is installed; the usual location is something
like ``C:\Python33``. Otherwise you will be reduced to a search of your whole
disk ... use :menuselection:`Tools --> Find` or hit the :guilabel:`Search`
button and look for "python.exe". Supposing you discover that Python is
installed in the ``C:\Python33`` directory (the default at the time of writing),
you should make sure that entering the command ::

c:\Python33\python

starts up the interpreter as above (and don't forget you'll need a ":kbd:`Ctrl-Z`" and
an ":kbd:`Enter`" to get out of it). Once you have verified the directory, you can
add it to the system path to make it easier to start Python by just running
the ``python`` command. This is currently an option in the installer as of
CPython 3.3.

More information about environment variables can be found on the
:ref:`Using Python on Windows <setting-envvars>` page.
