stream multiple camera using OpenCV

hey folks, recently I am working on a project which needs hand-on experience on OpenCV. As I am a newbie in the OpenCV framework I tried to use the basic kinds of stuff out of it, so I started to work with reading the camera and stream it. just simple and easy kind of stuff.

import numpy as np
    import cv2


    #capture the webcam
    vid1 = cv2.VideoCapture(0)
    vid2 = cv2.VideoCapture(1)
    vid3 = cv2.VideoCapture('http://192.168.2.2:5000/video') 
                                          #ipwebcam address 


    while True:                    #while true, read the camera
        ret , frame = vid1.read()
        re1 , frame1 = vid2.read()
        ret2 , frame2 = vid3.read()

        if (ret):
            cv2.imshow('cam0',frame)    #frame with name and 
                                        variable of the camera 
            cv2.imshow('cam1', frame1)
            cv2.imshow('cam3',frame2)

        if cv2.waitKey(1) & 0xFF == ord('q'):      #to break the 
                                    loop and terminate the program 
            break

    vid1.release()
    vid2.release()
    vid3.release()
