Get() method for dictionaries in Python
  • Difficulty Level : Easy
  • Last Updated : 25 Jan, 2018

In python dictionaries, following is a conventional method to access a value for a key.




dic = {"A":1, "B":2}
print(dic["A"])
print(dic["C"])

The problem that arises here is that the 3rd line of the code returns a key error :

Traceback (most recent call last):
  File ".\dic.py", line 3, in 
    print (dic["C"])
KeyError: 'C'

The get() method is used to avoid such situations. This method returns 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)



Example:




dic = {"A":1, "B":2}
print(dic.get("A"))
print(dic.get("C"))
print(dic.get("C","Not Found ! "))

Output:

1
None
Not Found !
