Question

So far I have:
x=raw_input("Enter a Sentence :")
i=0
while i <len(x):
i = i + 1
print(x[0:i])
that asks the user for an input and prints out the individual letters. I wanted to perform certain operations for individual characters and I was not quite sure how to refer to each character. For example, if I have a sentence: I like to eat apples how would I refer to the letter: k so that I can, let's say, turn it red using graphics import. (I'm not interested in knowing how to turn it red, just a way so I can refer to individual characters so I can write certain functions with them)
