Python | Difference in keys of two dictionaries
Given two dictionaries dic1 and dic2 which may contain same-keys, find the difference of keys in given dictionaries.
Code #1 : Using set to find keys that are missing.
# Python code to find the difference in # keys in two dictionary # Initialising dictionary dict1= {'key1':'Geeks', 'key2':'For', 'key3':'geeks'} dict2= {'key1':'Geeks', 'key2:':'Portal'} diff = set(dict2) - set(dict1) # Printing difference in # keys in two dictionary print(diff) |
Output:
{'key2:'}
Code #2 : Finding keys in dict2 which are not in dict1.
# Python code to find difference in keys in two dictionary # Initialising dictionary dict1= {'key1':'Geeks', 'key2':'For'} dict2= {'key1':'Geeks', 'key2':'For', 'key3':'geeks', 'key4': {'GeekKey1': 12, 'GeekKey2': 22, 'GeekKey3': 32 }} for key in dict2.keys(): if not key in dict1: # Printing difference in # keys in two dictionary print(key) |
Output:
key4 key3
Code #3: Finding keys in dict1 which are not in dict2.
# Python code to find difference in keys in two dictionary # Initialising dictionary dict1= {'key1':'Geeks', 'key12':'For'} dict2= {'key1':'Geeks', 'key2':'For', 'key3':'geeks', 'key4': {'GeekKey1': 12, 'GeekKey2': 22, 'GeekKey3': 32 }} for key in dict1.keys(): if not key in dict2: # Printing difference in # keys in two dictionary print(key) |
Output:
key12
Code #4 : Finding the same keys in two dictionaries.
# Python code to find difference in keys in two dictionary # Initialising dictionary dict1= {'key1':'Geeks', 'key2':'For'} dict2= {'key1':'Geeks', 'key2':'For', 'key3':'geeks', 'key4': {'GeekKey1': 12, 'GeekKey2': 22, 'GeekKey3': 32 }} print(set(dict1.keys()).intersection(dict2.keys())) |
Output:
{'key2', 'key1'}
