Build a Caesar Cipher - Step 15

Python
1

Tell us what’s happening:

I’m unclear what step 15 is asking to do and where the ‘upper’ needs to be added.

Your code so far

def caesar(text, shift):
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    shifted_alphabet = alphabet[shift:] + alphabet[:shift]

# User Editable Region

    translation_table = str.maketrans.upper(alphabet, shifted_alphabet)

# User Editable Region

    return text.translate(translation_table)

encrypted_text = caesar('freeCodeCamp', 3)
print(encrypted_text)

Hi @BrianL1018 ,

Update your str.maketrans() call by concatenating to each argument the uppercase version of the argument itself.

What are the two arguments passed to str.maketrans()? Take each argument and concatenate the same argument with upper() applied.

Happy coding!

3

The two arguments are alphabet and shifted_alphabet, but I am still lost on what to do

4

Do you understand how to concatenate one variable to another?

5

variable1 + variable 2

6

Okay, so take the first argument and concatenate it to the same first argument with upper() applied. What would that be?

7

alphabet+alphabet.upper()

shifted_alphabet+shifted_alphabet.upper()
