<s>[INST] ASCII value of a character in Python How do I get the ASCII value of a character as an int in Python?
 [/INST] From here:

function ord() would get the int value
  of the char. And in case you want to
  convert back after playing with the
  number, function chr() does the trick.

>>> ord('a')
97
>>> chr(97)
'a'
>>> chr(ord('a') + 3)
'd'
>>>

There is also the unichr function, returning the Unicode character whose ordinal is the unichr argument:
>>> unichr(97)
u'a'
>>> unichr(1234)
u'\u04d2'
