d = {1: "one", 2: "three"} d1 = {2: "two"} # updates the value of key 2 d.update(d1) print(d) d1 = {3: "three"} # adds element with key 3 d.update(d1) print(d) For better explanation you can read this post . https://www.google.com/amp/s/www.geeksforgeeks.org/JUMP_LINK__&&__python__&&__JUMP_LINK-dictionary-update-method/amp/

Thamarai Selvan Does something like this work? a = { 'a': 10, 'b': 20, 'c': 30 } b = { 'x': 200, 'y': 250, 'z': 300 } print( a, b, sep = '\n' ) a.update( b ) print( a )

update() method inserts the specified items to the dictionary. The specified items can be a dictionary, or an iterable object. dic1 = {1:'a', 2:'b'} dic2 = {2:'c', 3:'d'} dic1.update(dic2) print(dic1) Same as, dic = {1:'a', 2:'b'} dic[2]='c' dic[3]='d' print(dic) Output: {1:'a', 2:'c', 3:'d'}
