Tell us what’s happening:

dont understand how to concatenating each argument in the str.maetrans

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)

Welcome to the forum @friedrichguthaus,

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

Here’s the starting code:
translation_table = str.maketrans(alphabet, shifted_alphabet)

You have changed the existing arguments by applying upper(), but the instruction is to concatenate the upper() version of each argument to each existing argument.

str.maketrans(arg1 + arg1.upper(), arg2 + arg2.upper())

Happy coding
