Although you could use a list (Python's version of an array), you're 
better off using a dictionary here:

 >>> ports = {80:'HTTP', 70: 'Gopher', 79: 'finger'}
 >>> print ports[80]
HTTP

That way, you won't be wasting memory with a list thousands of items 
long were only a relative few are actually populated.

HTH,
