Get() method for dictionaries in Python
Python get() method return the value for the given key if present in the dictionary. If not, then it will return None (if get() is used with only one argument).
Syntax : Dict.get(key, default=None)
Parameters:
- key: The keyname of the item you want to return the value from
- Value: (Optional) Value to be returned if the key is not found. The default value is None.
Returns: Returns the value of the item with the specified key.
Python Dictionary get() method example
Example 1: Python get() method work for dictionaries
dic = { "A" : 1 , "B" : 2 } print (dic.get( "A" )) print (dic.get( "C" )) print (dic.get( "C" , "Not Found ! " )) |
Output:
1 None Not Found !
Example 2: Python Dictionary get() method nested
The get() to check and assign in absence of value to achieve this particular task. Just returns non-error None if any key is not present.
- Python3
# Python3 code to demonstrate working of # Safe access nested dictionary key # Using nested get() # initializing dictionary test_dict = { 'Gfg' : { 'is' : 'best' }} # printing original dictionary print ( "The original dictionary is : " + str (test_dict)) # using nested get() # Safe access nested dictionary key res = test_dict.get( 'Gfg' , {}).get( 'is' ) # printing result print ( "The nested safely accessed value is : " + str (res)) |
Output:
The original dictionary is : {'Gfg': {'is': 'best'}} The nested safely accessed value is : best
