You'll have to copy the list yourself. In your function you can do `b = b.copy()` Python passes everything "by reference" unless it's a primitive type (numbers, strings, booleans). That is to avoid unneccessary copying!

This is just an idea: the argument’s type is a memory adress, method p change the values contains in this adress, but the argument not change, its the same adress https://code.sololearn.com/c2l6WHeM6qPJ/?ref=app
