@savadkv01 This may be a problem with Pycharm, I guess you could also just silence the warning in the IDE, by adding a noinspection comment.
# noinspection PyArgumentList
cap = cv2.VideoCapture(0)
More information here: https://stackoverflow.com/questions/39929166/cv2-python-videocapture0-unexpected-argument
Hi, When I use python on command prompt also, same issue is getting.
C:\Users\Support ACTA>python Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.
import cv2 print(cv2.version) 4.5.3 cv2.VideoCapture(0) Traceback (most recent call last): File "

Linux version works as expected:

>>> import cv2 as cv
>>> qq = cv.VideoCapture(0)
>>> print(qq)
<VideoCapture 0x7f70094d7750>
I need some time to reproduce the same on Windows host and I'll come back.
Windows works ok for me:
