I finished the PygLatin exercise OK but I want to know what is exactly going on with the code:
What exactly is the len function doing when:
if len(original) > 0
I understand what the is.alpha does. That's simple. But what is 'len' doing and what does it mean when the code is checking > 0? No one is supposed to enter an integer/number anyway, right? So why check if the raw_input is greater than 0?
