怎滚滚滚么才能让插入的代码块不出错呢

import numpy as npimport cv2drawing=Falsemode=Trueix,iy=-1,-1def draw_circle(event,x,y,flags,param):    global ix,iy,drawing,mode#global 全局变量啊    if event==cv2.EVENT_LBUTTONDOWN:        drawing==True        ix,iy=x,y    elif event==cv2.EVENT_MOUSEMOVE and flags==cv2.EVENT_FLAG_LBUTTON:        if drawing==True:            if mode==True:                cv2.rectangle(img,(ix,iy),(x,y),(0,255,0),3)            else:                cv2.circle(img,(x,y),3,(0,0,255),-1)    elif event==cv2.EVENT_LBUTTONUP:        drawing==False        if mode==True:            cv2.rectangle(img,(ix,iy),(x,y),(0,255,0),3)        else:            cv2.circle(img,(x,y),5,(0,0,255),-1)        img=cv2.imread('C:\\Users\\WLX\\Desktop\\2.jpg',cv2.IMREAD_COLOR)cv2.namedWindow('image')cv2.setMouseCallback('image',draw_circle)while(1):    cv2.imshow('image',img)    k=cv2.waitKey(20)&0xFF    if k==ord('m'):        mode=not mode    elif k==27:        breakcv2.imwrite('C:\\Users\\WLX\\Desktop\\fsf.jpg',img)cv2.destroyAllWindows()haohaoxuexi
