Question

获取else语句右括号的无效语法错误，是由于缩进错误还是编码错误，我该如何解决。

font= cv2.FONT_HERSHEY_COMPLEX_SMALL
while(True):
ret,img=cam.read();
gray=cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
faces=faceDetect.detectMultiScale(gray,1.3,5)
for(x,y,w,h) in faces:
    cv2.rectangle(img,(x,y), (x+w,y+h),(0,0,255),2)
    id,conf=rec.predict(gray[y:y+h,x:x+w])
    if(conf<50):
     user=getUser(id)
     if(user!=None):
      cv2.putText(img,str(user[1]),(x,y+h),font,2,(0,255,0),2)
    else:
      cv2.putText(img,"Unknown"),(x,y+h),font,2,(0,255,0),2)#<-get invalid syntax for close bracket
cv2.imshow("Face",img);
if(cv2.waitKey(1)==ord('q')):
   break;
cam.release()
cv2.destroy.AllWindows()

您有一个额外的支架，请删除该额外的支架。

cv2.putText(img,"Unknown",(x,y+h),font,2,(0,255,0),2)
