A simple flake8 Plugin that checks if assert is used

The assert Keyword is very useful in Python, but has one big problem: Python has a optimized mode. When using this, The assert Keyword will no longer work, so if you use assert in a Library, this can lead to Problems.

You should replace assert with this little function:

def assert_func(expression: bool) -> None:
    """
    The assert keyword is not available when running Python in optimized mode.
    This function is a drop-in replacement.
    See https://docs.python.org/3/using/cmdline.html?highlight=pythonoptimize#cmdoption-O
    """
    if not expression:
        raise AssertionError()

This makes sure, your will be working.

If you just write your own Program, which you don't use with the optimized mode or if you use something like pytest, you can use assert of course.

This Plugin just checks for the use of the assert Keyword. Nothing more.
