hivert's solution is really good if you want to convert a range of numbers into characters, but if you have a pre-existing list of integers that you want to convert into characters, you could adapt the solution like this:
intList = [97, 98, 99, 100, 101, 102, 103, 104, 105, 106]
charList = [chr( intList[i] ) for i in range( 0, len( intList ) )]
