In the code below, the only part I'M having trouble with is word[position]. I know this is something really simple but I've always had trouble understanding these kinds of statements. I know that it prints a random letter (position) from (word). What I don't know is why or how it does that. That's the part that never seems to get explained to me. How can you just put  around part of a statement and everything just work right? Thanks. Please don't give me an answer like "because that's what's it mad to do. Explain it to me.
# Random Access # Demonstrates string indexing import random word = "index" print "The word is: ", word, "\n" high = len(word) low = -len(word) for i in range(10): position = random.randrange(low, high) print "word[", position, "]\t", word[position] raw_input("\n\nPress the enter key to exit.")
