Answer 1

Cause you didn't copied a string. On line 4 you created array (list) of characters. so "Hello"[0] == ["H", "e", "l", "l", "o"][0] (Both are "H"), but the string is not the same as array (list). you may want to try joining list to string:
>> "".join(["H", "e", "l", "l", "o"]) == "Hello"
so line 4 will look like this: cpy="".join([i for i in msg])
