Reversing a string sentence with a chain or list

Question

I tried to transform this sentence, "I am testing", into a list where each character is a value of the list and then return the reverse chain, like this: "gnitset ma I".

But when I try to run the program I met the error, IndexError:list assignment index out of range.

frase_lista = [""]
i = 0
for letter in "I am testing":
    frase_lista [i] = letter
    i += 1
print(frase_lista**)

Do you just want to reverse the string? – Fullstack Guy Sep 15 '19 at 19:00 — Fullstack Guy, Sep 15 '19 at 19:00
How about: `"I am testing"[::-1]` – user9074332 Sep 15 '19 at 19:16 — user9074332, Sep 15 '19 at 19:16

Maybe,

frase_lista = "I am testing"[::-1]    
print(frase_lista)

might be an option.

Or if you are reversing each word,

frase_lista = "I am testing".split()[::-1]

for i in frase_lista:
    print(i[::-1])

Output

gnitset
ma
I

Thank you for your help. Both options are useful. Also, I wanted to split each letter no each word and then, save it into a list. For instance, "Hello Emma" creates a list where each value is a letter: 'H' value [0] of the list 'e' value [1] etc. Thanks for your answer again. – Miguel Esteban Capdevila Sep 15 '19 at 19:33

You're trying to access an element frase_lista[i] which does not exist yet with i > 0. frase_lista has only one element "" that you add at the beginning. If you want to add more elements you should do the following:

frase_lista += [letter].

Also note that this won't reverse your list. To reverse the list you would need to add all letters starting from the end of the string, not from the beginning.
