1

Value = [(10,150),(100,200),(180,230)]
for i,(minVal,maxVal) in enumerate(Value):
    plt.subplot(1,3,i+1)
    edges = cv2.Canny(image,minVal,maxVal)
    edges = cv2.GaussianBlur(edges, (3,3), 0)
    plt.imshow(edges,'gray')
    plt.title(str((minVal,maxVal)))
    plt.axis('off')

2

x = ["id", "name", "age"]

y = [3306,"dh",18]

for i,j in zip(x,y):

    print(i,':',j,'\n')

监测键盘数据，等待q的输入

 # waitKey功能是不断刷新图像，单位ms，返回值是当前键盘按键值
 # ord返回对应的ASCII数值
 if cv2.waitKey(1) & 0xff == ord('q'):
     break
