common value in python dictionaries

Question

map1 = { 1: "Sam", 2: "Rich", 3 : "Mike", 4: "Bob", 6: "Donald"}
map2 = { 5: "Sally", 6 : "Donald", 7: "Roger", 1: "Sam"}

I want to print common names in both dicts, Can anyone help me out

Answer 1

You can recover your values with dict.values and cast them to sets. This allows you to find their intersection.

print(set(map1.values()) & set(map2.values()))

Answer 2

Try this using set

map1 = { 1: "Sam", 2: "Rich", 3 : "Mike", 4: "Bob", 6: "Donald"}
map2 = { 5: "Sally", 6 : "Donald", 7: "Roger", 1: "Sam"}

list(set(map1.values()).intersection(set(map2.values())))

it returns list with common values in both dictionary

Answer 3

set(map1.values()).intersection(set(map2.values()))
