i want to make a program that searches the wally.

this is a code:

import bumpy as np

import cv2

import matplotlib.pyplot as pat





img1=cv2.imread(‘icy.jpg’,0)

img2=cv2.imread(‘wally.png’,0)

sift=cv2.xfeatures2d.SIFT_create()

kp1,des1=sift.detectAndCompute(img1,None)

kp1,des2=sift.detectAndCompute(img2,None)

bf=cv2.BFMatcher()

matches=bf.knnMatch(des1,des2,k=2)

good=[]




for m,n in matches:
    if m.distance<0.75*n.distance:
        good.append([m])





img3=cv2.drawMatchesKnn(img1,kp1,img2,kp2,good,None,flags=2)

plt.imshow(img3)


plt.show()

But i have another errors.

this is a error: syntaxerror keyword can't be an expression

I don't understand what they say
