Python Dictionary get function is used to return value at a given key position. In this section, we discuss how to use this Dictionary get function. The syntax behind this Python dict get function is:
dictionary_name.get(key, default_value)
Python Dictionary get Example
The Python dict get function returns the value at the specified user key.
TIP: Please refer to the Dictionary in Python.
myDict = {1: 'apple', 2: 'Banana' , 3: 'Orange', 4: 'Kiwi'}
print("Dictionary Items: ", myDict)
print("\nValue of Key 2 : ", myDict.get(2))
print("Value of Key 3 : ", myDict.get(3))
print("Value of Key 4 : ", myDict.get(4))
print("Value of Key 1 : ", myDict.get(1))
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 dict key. As you can see, it returns None because key is not present.
However, you can use the second argument to specify the default value for non-existing values. Here, the last line of code searched in the dictionary and returns default value Mango.
myDict = {1: 'apple', 2: 'Banana' , 3: 'Orange', 4: 'Kiwi'}
print("Items: ", myDict)
print("\nValue of Key 4 : ", myDict.get(4))
print("Value of Key 5 : ", myDict.get(5))
print("\nValue of Key 6 : ", myDict.get(6))
print("Value of Key 6 : ", myDict.get(6, 'Mango'))
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
