Tell us what’s happening:

Not sure how to use bracket notation to access the first letter in text and try to change it into a character of your choice.

Your code so far


/* User Editable Region */

text = 'Hello World'
text = 'X' + text[1:]


/* User Editable Region */

shift = 3
alphabet = 'abcdefghijklmnopqrstuvwxyz'

for char in text.lower():
    index = alphabet.find(char)
    print(char, index)
    new_index = index + shift

Hello Binarycoder,

This one was a bit tricky, it’s trying to make you do something that isn’t possible on purpose.

So to access the first character of a string you can use string_var[0]. So in this case it would be text[0].

Now comes the tricky part though, normally to assign a variable you would just do variable = "something". It wants you try and do something similar with the first letter of text so you learn that you aren’t able to do so.

If you’re still stuck, you will see the answer here:

Answer 
text = 'Hello World'
text[0] = 'x'
