Build a Caesar Cipher - Step 15

Python
1

Tell us what’s happening:

I do not get the instructions. All of the character are capitalized. Here is what I have:

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

I also tried translation_table = alphabet.upper() + shifted_alphabet.upper())

translation_table = str.maketrans(alphabet.upper() + shifted_alphabet.upper())
return text.translate(translation_table)

Your code so far

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

# User Editable Region

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

# User Editable Region

    return text.translate(translation_table)

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

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

This instruction asks for something more like this:

str.method(argument + argument.upper())

I see the issue. I did not separate the maketrans method with a comma. I think I still get the same results with the code above. Why is the comma needed?

4 
str.maketrans(alphabet, shifted_alphabet)

There are two arguments. Comma separates the arguments.

I was confused with this part as well; I just didn’t understand correctly. Running theme I am having. But I was able to pass it by adding the arguments twice, one with no upper and one with upper, and concatenating (adding) them together, then separating them with a comma between alphabet and shifted_alphabet.
