dictionary = {0: 'zero', 1: 'one', 2: 'two', 3: 'three'}
list1 = [zero, one, two]

I want to delete the entry '3:three' from the dictionary since it is not in the list. I am retaining only the common entries in the list. How can I do it??? :confused:

Syntax: Select all

dictionary = {0: 'zero', 1: 'one', 2: 'two', 3: 'three'}
list1 = ['zero', 'one', 'two']

for key, value in tuple(dictionary.items()):
    if value not in list1:
        del dictionary[key]
        
print(dictionary)
