CV2 Python VideoCapture(0) unexpected argument

I have a short python script that will open the webcam and display a live feed on a local web site. I am using PyCharm IDE which offers corrections and notify's you in case of syntax error. When I pass an argument to VideoCapture it highlights it and says 'unexpected argument'.

self.video = cv2.VideoCapture(0)

This is in a class and the 'unexpected argument is caused by the 0 that is passed to the OpenCV function. Is there any way I can fix this?

By the way it works fine as is - when you run it, it works the way it should. If you remove the zero the error goes away but it no longer initializes the webcam.

Instead of hacking in the incorrect bindings, you could also just silence the warning in the IDE, by adding a noinspection comment.

# noinspection PyArgumentList
cap = cv2.VideoCapture(filename)

I think you are right and Hector-the-Inspector of PyCharm IDE is wrong. So go to the line with warning and suppress the warning for this statement: put cursor on the statement, go to the bulb icon, click on triangle in the right corner, in the menu choose "Suppress for statement".
