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

Thanks!
Try int.
ie.
try:
int_val = int(str_val)
except ValueError:

How do I go about modifying one character in a string elegantly?
In other words, I want a function that will change '' to 'aaza',
given the index 2 of the character in the string.
Also, how do I do this when dealing with a file ; which file mode
should I use and

If you don't need you program to be portable you can use extensions -

Ahem, who use python. For jython this looks like
True != False

type(True)

Hi Kier,
Any idea where I'd find documentation on using this extension? I've

As it's a windows version of the standard readline module (usually

I'd _guess_ that you could
You may also find the cmd module useful, see:

Fred,
It is quite possible I've misunderstood the problem :-) but have
you tried anything like
import socket
tc_local_port =
tc_remote_port =

remote_tc_host = 172.16.1.3 # say
# udp is the default for DGRAM

A few trivial corrections, to my own post :-(
tc_sock = socket(socket...
should be
tc_sock = socket.socket(socket...
of course
and, (while I'm here) when I stated that calling connect on an
unbound socket caused
a ephemeral port to be assigned, I should have written calling connect

I wouldn't, especially[1] if your thousands of business objects get
allocated/deallocated as the system runs. Currently python's memory
usage can grow rapidly (from the perspective of the o/s) when large
numbers of objects are repeatedly created and freed.
Isn't it true that in recent Python
I'd use the int and chr casts. e.g.,
new_string =
a = '012'
new_string += chr(int(a))
Just in case the 012 is an octal code I'll mention that to cast to int
in general you can pass the base, as in int('034',8) or int('AF',16)
