No.  One of the fundamental concepts of Python is that it completely 
hides the physical memory.  Sure, at some point, when you write

x = 42

it allocates some piece of memory and puts the integer 42 into it, but 
all those details are hidden from you (and are implementation specific).

I think what you're talking about is the ord() function.  Given a single 
character (i.e. a string of length 1), it returns the unicode value for 
that character.  Thus:

>>> ord('X')
88

You could iterate over the characters in a string to find that for each 
one:

>>> [ord(c) for c in "My string"]
[77, 121, 32, 115, 116, 114, 105, 110, 103]

This is starting to sound like a homework problem, or possibly an 
interview question :-)
