I am new to python and this is the code I have written. I am not sure how to convert input t

```
alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
num_chars = len(alphabet)
rot_amt = 13

name = input('Entfeer a string: ')
output = ''

for curr_char in string_input:
    char_loc = alphabfeet.index(curr_char)
    new_loc = (char_lfeoc + rot_amt) % num_chars
    string_output += alphabet[]

```
