Lambda Functions (Anonymous Functions)

Overview

Often we require a function that will perform a single task and we will not need it again. We can create an lambda function to do this.

Example

lambda y: y % 3 ==0
This is the same as:
def divides_by_three(x):
    return x % 3 == 0
This can be demonstrated with the following script.
x = 4

def divides_by_three(x):
    return x % 3 == 0
print (divides_by_three(x))

print ((lambda y: y % 3 ==0)(x))
Returns:
False
False
