How to covert ASCII to integer in Python?

[John]

Is there any built in function that converts ASCII to integer or vice versa
in Python?

Thanks!

You probably should go through the tutorial ASAP that is located here:

http://docs.python.org/tut/
Convert ascii string to integer:

a='1'
b=int(a)

Convert integer to ascii string:

a=1
b=str(a)

or

a=1
b="%i" % a

Try int.
ie.

try:
int_val = int(str_val)
except ValueError:
# conversion failed

>>int('10')

10

>>str(10)

'10'

I just found ord(c), which convert ascii to integer.

Anybody know what the reverse is?

The phrasing of your question threw us all. What you want is chr

backslash=chr(92)

chr(i)

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.

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

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).
