[Tutor] Noob to Python - Need help with Variables

[Tony Stevenson]

 Hi All, 

I am completely new to programming, so I thought I would start with Python
as it comes highly reccomended, and have seen it do some very smart
things.

Anyway, I am trying to re-write our somewhat painful DOS Batch File
Logon Scripts. 

I am currently using   print os.environ["USERNAME"]   to obtain the
username environment variable.

Now I will be using this entry several times throughout the script, so I
"thought" I would need to create a variable in python.  But after trying
this    

>>> user = "print os.environ['USERNAME']"
>>> print user

This is what is returned....    


print os.environ['USERNAME']



So I can see that the "variable"??? user, it not executing the print
os.environ command.  Instead is it using it as a text entry.


My question is how can I get this "user variable" to return the username
in question. 

I think i may be missing a pair of quotes or something, but I am not too
sure... 



Kind Regards,
Tony
