Why are Python lambdas useful

Question

What is the advantage of using Python lambda?

Answer 1

The main purpose of anonymous functions come into picture when you need some function just once. They can be created wherever they are needed. Due to this reason, Python Lambda Functions are also known as throw-away functions which are used along with other predefined functions such as filter(), map(), etc. These functions help reduce the number of lines of your code when compared to normal Python functions.

Example:

def new_func(x):

    return(lambda y: x+y)

t=new_func(3)

print(t(3))

Output: 6
