[Tutor] How do I get Dos to recognize python command?

[Kermit Rose]

I followed the model in 
 
http://www.byteofpython.info/read/source-file.html 
 
and saw following results. 
 
 
C:\DavidKaremera\June2006\SAS>python med.py 
'python' is not recognized as an internal or external command, 
operable program or batch file. 
 
 
What do I do to make DOS recognize python as a command? 
 
 
The link http://hkn.eecs.berkeley.edu/~dyoo/python/idle_intro/index.html 
that you suggested 
 
shows information about the idle. 
 
I've used idle for development until now, but it has the annoyance 
that I must close it and reopen it in order for it to import the changed
copy 
of the program. 
 
Besides, I already have one default module saved, and it would seem 
complicated to have more than one. 
 
It would be simpler if I can get the dos prompt to work.
