'taking webcam photos in python 3 and windows

I want to be able to take a photo from a webcam in python 3 and Windows. Are there any modules that support it? I have tried pygame, but it is only linux and python 2, and VideoCapture is only python 2.

You can download "pygame?1.9.2a0.win32?py3.4.exe"

take a photo from a webcam in python 3.4 (testing on window 7) code [1]

import pygame
import pygame.camera

pygame.camera.init()
cam = pygame.camera.Camera(0,(640,480))
cam.start()
img = cam.get_image()
pygame.image.save(img,"filename.jpg")

import cv2

# Open the device at the ID 0 
cap = cv2.VideoCapture(0)

 #Check whether user selected camera is opened successfully.

if not (cap.isOpened()):

    print("Could not open video device")

#To set the resolution 
    cap.set(cv2.cv.CV_CAP_PROP_FRAME_WIDTH, 640)

    cap.set(cv2.cv.CV_CAP_PROP_FRAME_HEIGHT, 480)

while(True): 
# Capture frame-by-frame

    ret, frame = cap.read()

# Display the resulting frame

    cv2.imshow('preview',frame)

#Waits for a user input to quit the application

if cv2.waitKey(1) & 0xFF == ord('q'):
     #break

# When everything done, release the capture 
    cap.release()

    cv2.destroyAllWindows()
