Tell us what’s happening:

i cant pass this lesson because it always show “You should modify the arguments of your str.maketrans() call by concatenating to each argument the uppercase version of the argument itself.”. The console show freefodefamp i know it should be freecodecamp but how

Your code so far

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

# User Editable Region

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

# User Editable Region

    return text.translate(translation_table)

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

Do you know what concatenating a string is?

You have 2 arguments. You need to add the uppercase version of the argument to itself.

So, if the argument is “test” you need to change it to "test" + "test".upper()

The example code shows how to change a string to uppercase. Now you need to concatenate.

Hey, there in the instructions it is mentioned that “all by concatenating to each argument the uppercase version of the argument itself.” which means you need to concatenate the text with its uppercase version as well, like this:
translation_table = str.maketrans(alphabet, shifted_alphabet)

hi @neonbit01

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
