The Lambda function is a one-liner alternative to the regular functions. It can be defined in a single line of code and thus takes less time and space in our code. For example, in the below code, we can see multiple examples of replacing a regular function with a lambda function.

Function with one argument

##Regular function

def multiply_by_2(x):

return x*2

##lambda function

lambda x: x*2

Function with 2 or more arguments

##Regular function

def multiple_three_numbers(x,y,z):

return x*y*z

##lambda function

lambda x, y, z: x*y*z

Note: The lambda function cannot replace loop in python but we help us to convert a muli-line functionality into one-liner.
