What does the program print?

Python

word = "python"
print(word[-1], word[-6], len(word))

n p 6

Expecting an IndexError for word[-6]: negative indices run from -1 down to -len(word), so -6 is the first character of a 6-letter word.
Expecting 5 for len(word), as if it gave the last index: len counts the characters, 6, while the last index is 5, which is -1.
