| I'm writing a program that requires some string manipulations. Let's say
| I have a string
|
| s='x'
|
| Now, the ascii code for 'x' is 0x78. I want to be able to perform
| operations on this number, and print the character corresponding to the
| results of the operation. For example, the pseudo-code looks like:
|
| -read in string s from external file (for simplicity, we'll keep s='x')
|
| -determine the code for s (should be 0x78 or 120 in base 10), store it in
| variable c
|
| -add a literal to c (let's say c=c+1)
|
| -find out which character corresponds to the new code c=0x79
|
| -store the character in a new string s2
|
| At the end of this, I want s2='y'
|
| Any suggestions?

Take a look at the built-in functions ord() and chr() -- Chapter 2.1 of the
manual.

>> s = 'x'
>> c = ord(s)
>> c
120
>> c+=1
>> s2 = chr(c)
>> s2
'y'
