Build a Caesar Cipher - Step 15

Tell us what’s happening:

I need help with concatenating the string to make it uppercase

Your code so far

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

# User Editable Region

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

# User Editable Region

    return text.translate(translation_table)


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