Hello everyone who can help with implementing a bracket correctness check using a stack in Python. I know the essence of the check, and I implemented it through conditions, but I can't understand how to do it with a stack, please help. 

   def   brackets_check  ( s ): meetings =  0    for  c  in  s:   if  c ==  '(' :  meetings +=  1
