Python 3 throws an error message on the original assert statement. Also, according to the Python documentation regarding the assert statement (https://docs.python.org/3/reference/simple_stmts.html#the-assert-statement), `assert` takes at least one argument and at most two. In the two-argument form the second argument is meant as an error message to be displayed when the assertion fails. I don't think this is intended in this case.
I'm using SpaCy version 2.0.3. If I don't use the *-operator in the example, Python throws an error message. With the operator it works fine. Also according to the documentation of the function `nlp.disable_pipes()`, it expects one or more strings as arguments and not one argument being a list of strings.
