Hello can someone help me understand this well?

Question

code = input()[::-1]

spell = ""

letters = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', ' ' ]

for i in range(len(letters)-1):
letters.append(letters[i].upper())

for i in code:
if i in letters:
spell += i

print(spell)

Answer 1

Your code basically, takes an input as a string. If the string includes the given letters, reverses it and print the reversed string.

I hope, it's clear. Happy coding!
