Thank you for teaching Python to beginners!

Yes, it is. That's why Python 3 forbids it::
>>> True = "shadow"
File "<stdin>", line 1
SyntaxError: can't assign to keyword
>>> False = "light"
File "<stdin>", line 1
SyntaxError: can't assign to keyword
When teaching Python, please do not teach Python 2. Your students should
learn Python 3 first, primarily, and for most of the course.
Python 2 is a legacy that will never gain new features, and will only
slip further behind the current supported Python version. That makes
Python 2 a poor choice for teaching to beginners.
