Tell us what’s happening:

There is a name error on line 14… Where it says encrypted_text is not defined. Ive tried to correct but it wont change anything…

Your code so far


# User Editable Region

text = 'Hello Zaira'
shift = 3
def caesar():
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    encrypted_text = ''
    for char in text.lower():
        if char == ' ':
            encrypted_text += char
        else:
            index = alphabet.find(char)
            new_index = (index + shift) % len(alphabet)
            encrypted_text += alphabet[new_index]
print('plain text:', text)
print('encrypted text:', encrypted_text)

this print is outside the function, encrypted_text exists only inside the function

what were you asked to do with the two print statements?

Right after your shift variable, declare a function called caesar and indent all the following lines to give your new function a body.

Once that was done it required everything that was under the shift=3 variable be indented and now it wont work no matt
er what i do…

4

and did you indent all of the lines? all of them?

def caesar():
    text = 'Hello Zaira'
    shift = 3
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    encrypted_text = ''
    for char in text.lower():
        if char == ' ':
            encrypted_text += char
        else:
            index = alphabet.find(char)
            new_index = (index + shift) % len(alphabet)
            encrypted_text += alphabet[new_index]
            print('plain text:', text)
            print('encrypted text:', encrypted_text)

After i was advised to put all the outside variables into the new function or change them into parameters and am still stuck

follow the step instructions only

where the two print statements inside the else before creating the function?

7

idk how to do it and i think i did… Mde sure where a required indent was needed after the colon was indented and still dont know…

8

no they were not… the initial problem wanted them inside so i did it and now its the indent problem…

9

inside what? the else? or only the function?

10

to put things inside the function you needed to indent only 4 spaces, the print statements are indented 12 spaces more than they were before, that’s a great change

the function i think… (…)

what are you going to do now?

Thank you it worked finally…

I deleted the extra indents until the prints were at the end of the for loop
