Tell us what’s happening:

I am stuck at this step, thinking that I have made it right, but I am still not moving forward. Thus, I needed someone’s help. Please
def caesar(text, shift) → str:
if not isinstance(shift, int):
return “Shift must be an integer value.”

if shift < 1:
    return "shift must be a positive integer."

Your code so far


# User Editable Region

def caesar(text, shift) -> str:
    if not isinstance(shift, int):
        return "Shift must be an integer value."
    
    if shift < 1:
        return "shift must be a positive integer."

# User Editable Region

    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    shifted_alphabet = alphabet[shift:] + alphabet[:shift]
    translation_table = str.maketrans(alphabet + alphabet.upper(), shifted_alphabet + shifted_alphabet.upper())
    return text.translate(translation_table)


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