Get () method for dictionaries in Python



dic = { " A " : 1 , "B" : 2 }

print (dic [ "A" ])

print (dic [ "C" ])

The problem that comes up here is that the 3rd line of 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, by default = No)

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!
