How to check if a key-value pair is present in a dictionary?

Question

Is there a smart pythonic way to check if there is an item (key,value) in a dict?

a={\'a\':1,\'b\':2,\'c\':3}
b={\'a\':1}
c={\'a\':2}

b in a:
--> True
c          


        

Answer 1

   a.get('a') == 1
=> True
   a.get('a') == 2
=> False

if None is valid item:

{'x': None}.get('x', object()) is None
