Sure, but if that was the OP's intent he would most likely have mentioned it... As others have already guessed, it's most likely somethink like ord() he was after. cu Philipp -- Dr. Philipp Pagel Lehrstuhl f.

Oops! I meant ord(a)-64, of course.

Possibly. Perhaps the OP wants the position of 'P'
in the alphabet, in which case he wants b=64-ord(a)
or b=16.

int() converts a strings that is a valid intenter. What you're looking for
is ord().
In [1]: ord('d')
Out[1]: 100
In [2]: a='P'
In [3]: b=ord(a)
In [4]: b
Out[4]: 80
j

You really don't see any difference between "convert '1' to an integer" and "convert 'P' to an integer"? In case there's actually a problem you're trying to solve here, try ord instead of int. > Or probably you yourself should - quote : > "You probably should go through the tutorial ASAP that is located here: > > http://docs.python.org/tut/ " > > - > [Image] -- David C.

ord('\xff') -> 255
ord(unichr(666)) -> 666
What ascii?
What is stopping you from reading the documentation section on built-
in functions (http://docs.python.org/lib/built-in-funcs.html)?
That way, you might find an answer to whatever your question really
is, without wasting time (yours and that of others trying to guess).

In the versions of Basic that I've seen they were ASC (clearly ASCII)
and CHR$. I first saw ord in Pascal.

The inverse of "ord" is "chr":
% python
Python 2.5 (r25:51908, Jan 5 2007, 00:12:45)
[GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> ord('i')
105
>>> chr(105)
'i'
>>>
IIRC, the first use of the names "ord" and "chr" for these functions
appeared in the Basic language in the 1960's ... in case anyone is
interested in this bit of historical trivia.

Re: How to covert ASCII to integer in Python?
Or perhaps...
ord ("a")
97
chr (97)
'a'
