 # Hello World
 
 以下 `Hello World` 程序中，能够正确执行下述操作的是？
+
 1. 读取目录下`lena`图片
 2. 显示`lena`图像窗口
 3. 等待用户输入任意按键后关闭窗口
+4. 销毁所有窗口
 
 ## 答案
 
-```cpp
-#include <opencv2/opencv.hpp>
-using namespace cv;
-
-int main() {
-  Mat img = imread("lena.png");
-  imshow("lena", img);
-  waitKey(0);
-  destroyAllWindows();
-  return 0;
-}
+```python
+import cv2
+
+if __name__ == '__main__':
+    img = cv2.imread("lena.png")
+    cv2.imshow("lena", img)
+    cv2.waitKey(0)
+    cv2.destroyAllWindows()
 ```
 
 ## 选项
 
 ### 没有显示图像
 
-```cpp
-#include <opencv2/opencv.hpp>
-using namespace cv;
+```python
+import cv2
 
-int main() {
-  Mat img = imread("lena.png");
-  waitKey(0);
-  destroyAllWindows();
-  return 0;
-}
+if __name__ == '__main__':
+    img = cv2.imread("lena.png")
+    cv2.waitKey(0)
+    cv2.destroyAllWindows()
 ```
 
 ### imshow参数顺序错误
 
-```cpp
-#include <opencv2/opencv.hpp>
-using namespace cv;
-
-int main() {
-  Mat img = imread("lena.png");
-  imshow(img, "lena");
-  waitKey(0);
-  destroyAllWindows();
-  return 0;
-}
+```python
+import cv2
+
+if __name__ == '__main__':
+    img = cv2.imread("lena.png")
+    cv2.imshow(img, "lena")
+    cv2.waitKey(0)
+    cv2.destroyAllWindows()
 ```
 
 ### 忘记销毁窗口
 
-```cpp
-#include <opencv2/opencv.hpp>
-using namespace cv;
+```python
+import cv2
 
-int main() {
-  Mat img = imread("lena.png");
-  imshow("lena", img);
-  waitKey(0);
-  return 0;
-}
+if __name__ == '__main__':
+    img = cv2.imread("lena.png")
+    cv2.imshow("lena", img)
+    cv2.waitKey(0)
 ```
 
 ### 没有等待用户输入按键
 
-```cpp
-#include <opencv2/opencv.hpp>
-using namespace cv;
-
-int main() {
-  Mat img = imread("lena.png");
-  imshow("lena", img);
-  destroyAllWindows();
-  return 0;
-}
-```
