for index, letters in enumerate('abcdefghijklmnopqurstuvwxyz'):
print("{} : {}".format(index,letters))
Why did instructor use index+1? I get same output without it. It always makes me annoying when someone uses count or index in code. I don't think instructor did great job in explaining those keywords at all.
