For example, I would like to make a code like this:
while True:
[...]
if <left mouse button is clicked>:
print("Left Mouse has been clicked")
[...]
cv2.destroyAllWindows
I've the the "Mouse as a Paint-Brush", but it does not explain how to have python just recognize the mouse left click event.
I'd appreciate any help I can get.

I'd tried modifying the code from the tutorial to suit my needs, but I can't seem to get the code to work:
def mouse(event,x,y,flags,param):
if event == cv2.EVENT_LBUTTONDBLCLK:
return True
[...]
cap = cv2.VideoCapture(0)
while True:
[...]
if cv2.setMouseCallback('frame', mouse)==True
print("Left Mouse Button has been clicked")
[...]
cv2.destroyAllWindows

[Update]
I managed make progress by using the following code I modified from the more advanced example on the "Mouse as a Paint-Brush" tutorial. I modified the code for the purpose of having OpenCV recognize a mouse left-button click on a live webcam:
[...]
cap = cv2.VideoCapture(0)
drawing = False
def draw_circle(event,x,y,flags,param)
global drawing
if event == cv2.EVENT_LBUTTONDBCLK:
drawing = True
while True:
[...]
drawing = False
cv2.setMouseCallback('frame',draw_circle)
if drawing == True:
print("Left Mouse Button has been clicked.")
[...]
cv2.destroyAllWindows
