d1 = {
	"1" : 1,
	"2" : 2,
  	"3" : 3
} # Define the dictionary

d1["4"] = 4 # Add key-value pair "4" is key and 4 is value

print(d1) # will return updated dictionary

testing1={'one':1,'two':2}
''' update() is the method of dict() merges another dict into existing ones '''
''' it replaces the keys of exisiting ones with the the new ones '''
testing1.update({'two':3,'noice':69}) 
print(testing1) """ {'one':1,'two':3,'noice':69} """
