Lambda Function

#python #programming #functional

• They are anonymous function, they do not receive name
• If they are too complex transform them into def, or, normal function
• Can be used the Walrus operator to assign instead of the =, however, it is not recommended
• They are used as argument for high order functions

>>> fruits = ['strawberry', 'fig', 'apple', 'cherry', 'raspberry', 'banana']
>>> sorted(fruits, key=lambda word: word[::-1])
['banana', 'apple', 'fig', 'raspberry', 'strawberry', 'cherry']
