Can someone correct my logic!

Question

Here is the code:
words=['cat', 'dog', 'rabbit']
letters=[]
for aword in words:
for aletter in aword:
letters.append(aletter)
print(letters)

What I do not understand is why " letters.append(aletter)" to me that is like asking python to add letters at the end of the list words. Making ['cat', 'dog', 'rabbit', 'c', 'a', 't', 'd'...] and so on. Append means add an item to a list. Can someone correct my logic?

Answer 1

So... append your letters to words, not letters: words.append(aletter). Logical error, bro :)
btw: you don't need letters list at all. If wyou want to keep it, create letters as a copy of words first: letters = words. In that case your code your code will give you expected result, words first and letters after them.
