Stef, "it doesn't work" is user-speak. Say what what you expected, and
what happened instead.

That is equivalent to:
code = "multiline comment\nand morelines"
exec(code)
which of course produces a Syntax Error. What did you expect?
Oh, yeah, the so-called "multiline comment". I can't imagine why you
want to put comments in code that you're going to exec, but you need
an extra layer of quotes:
Code += '''"""multiline comment
and more lines"""'''
