#include /* foreach macro viewing an array of int values as a for key, value in some_dict.items(): # Direct iteration on a dict iterates

for k , v in d . items (): print ( k , v ) # key1 1 # key2 2 # key3 3 2020-07-09 · We can access the items method and iterate over it getting each pair of key and value. Example. Live Demo.

2020-06-04 · If the value matches the key is returned. Example. Live Demo. dictA = {"Mon": 3, "Tue": 11, "Wed": 8} def GetKey(val): for key, value in dictA.items(): if val == value: return key return "key doesn't exist" print(GetKey(11)) print(GetKey(3)) print(GetKey(10)) Output.
