[Tutor] I have a problem with def

[David Bauer]

it doesn't work, you are suppsed to declare a function as def func() and it
comes back as:

File "<stdin>", line 1
    def func()
             ^
SyntaxError: invalid syntax

that is not expected I would also expect def to turn red because it is a
keyword in Python, but that doesn't happen, anyone else having this
problem???? Anyone know what I should do or look for????
