Dictionary setdefault() Method
Description
Python dictionary method setdefault() is similar to get(), but will set dict[key]=default if key is not already in dict.
Syntax
Following is the syntax for setdefault() method −
dict.setdefault(key, default=None)
Parameters
key − This is the key to be searched.
default − This is the Value to be returned in case key is not found.
Return Value
This method returns the key value available in the dictionary and if given key is not available then it will return provided default value.
Example
The following example shows the usage of setdefault() method.
dict = {'Name': 'Zara', 'Age': 7} print "Value : %s" % dict.setdefault('Age', None) print "Value : %s" % dict.setdefault('Sex', None)
