How do I convert a list of ascii values to a string in python?

Question

I've got a list in a Python program that contains a series of numbers, which are themselves ASCII values. How do I convert this into a "regular" string that I can echo to the screen?

Answer 1

You are probably looking for 'chr()':

>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(chr(i) for i in L)
'hello, world'

Answer 2

l = [83, 84, 65, 67, 75]

s = "".join([chr(c) for c in l])

print s

Answer 3

Same basic solution as others, but I personally prefer to use map instead of the list comprehension:

>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(map(chr,L))
'hello, world'

Answer 4

import array
def f7(list):
    return array.array('B', list).tostring()
