args和*kwargs是python中经常使用的函数参数，代表着函数的参数数目是可变的。为讲解清楚两个参数的意义，以下一段代码为例做讲解：def fun(*args,**kwargs):print "args = ",argsprint "kwargs = ",kwargs(1)fun(1,2,3,4)输出结果：args= (1, 2, 3, 4)kwargs= {}说明：在f...

Opencv对于图片的处理（使用的BGR模式，不是RGB模式）Img = cv2.imread(image0.jpg,1)#有两个参数，参数一是图片的名称，参数二是图片的类型（0是灰度图，1是RGB）cv2.imshow(‘image,img)#有两个参数，参数一是窗体的名称，参数二是要显示的图片Cv2.waitkey(0)#停止操作，0毫秒Cv2,imwrite(‘image1.jpg’...
