How to detect mouse events (left click) with Python

You can use the win32api to check for any key presses, including mouse events.

1. # Code to check if left or right mouse buttons were pressed 
2. import win32api 
3. import time 
4.  
5. state_left = win32api.GetKeyState(0x01) # Left button down = 0 or 1. Button up = -127 or -128 
6. state_right = win32api.GetKeyState(0x02) # Right button down = 0 or 1. Button up = -127 or -128 
7.  
8. while True: 
9. a = win32api.GetKeyState(0x01) 
10. b = win32api.GetKeyState(0x02) 
11.  
12. if a != state_left: # Button state changed 
13. state_left = a 
14. print(a) 
15. if a < 0: 
16. print('Left Button Pressed') 
17. else: 
18. print('Left Button Released') 
19.  
20. if b != state_right: # Button state changed 
21. state_right = b 
22. print(b) 
23. if b < 0: 
24. print('Right Button Pressed') 
25. else: 
26. print('Right Button Released') 
27. time.sleep(0.001)
