Removing the protection of Windows for serial communication

I am running an Arduino on the USB serial port. I am trying to access the data from the serial port and print it on the python output terminal. However, when I get this error message from python:

File "C:\Users\User\anaconda3\Lib\site-packages\serial\serialwin32.py", line 64, in openraise SerialException("could not open port {!r}: {!r}".format(self.portstr, ctypes.WinError()))serial.serialutil.SerialException: could not open port 'com3': PermissionError(13, 'Access is denied.', None, 5)

I know this is the Windows trying to protect me but I need to turn it off for some time. How do I do this?
