##KingMrMonopoly: Hello I’m having a problem with this line of code anything that you suggest I do different?

Your code so far


/* User Editable Region */

text = 'Hello World'
shift = 3
alphabet = 'abcdefghijklmnopqrstuvwxyz'
index = alphabet.find(text[0].lower())
print(index)
shifted = alphabet.find(text[7].lower()) + shift

Use the format variable = string[var1 + var2]

You are correct up to this point:

shifted = alphabet

Do you remember how to access a letter position of a string? text[0] accesses the letter at the first (0) position of text.

You want to access a letter in the string alphabet at the position index + shift

Try these steps:

  • declare a variable named shifted and assign it the string alphabet
  • modify the assignment into alphabet at position index using square brackets
  • modify the position in the square brackets to index + shift

You know if you want to access the h in alphabet would be alphabet[7] since you already found the position. Now you want to slide 3 (stored in the shift variable) letters down the alphabet from h and get that letter.
