Python dict get Example 2
In this Python dict get program, we are using the second argument to display the default value. First, we are trying to access the non-exiting key. As you can see, it returns None. However, you can use the second argument to specify the default value for non-existing values. Here, the last line of code returns Mango as the default value.
# Python Dictionary get Example
myDict = {1: 'apple', 2: 'Banana' , 3: 'Orange', 4: 'Kiwi'}
print("Dictionary Items: ", myDict)
# Get Value
print("\nValue of Key 4 : ", myDict.get(4))
print("Value of Key 5 : ", myDict.get(5))
# Get Value with Default Value
print("\nValue of Key 6 : ", myDict.get(6))
print("Value of Key 6 : ", myDict.get(6, 'Mango'))
Dictionary Items: {1: 'apple', 2: 'Banana', 3: 'Orange', 4: 'Kiwi'}
Value of Key 4 : Kiwi
Value of Key 5 : None
Value of Key 6 : None
Value of Key 6 : Mango
