Recursion in lambda function in python by R4R Team

Lambda function-
-In Python, anonymous function means that a function is without a name. As we already know that def keyword is used to define the normal functions and the lambda keyword is used to create anonymous functions.

Syntax-

lambda argument:expression

Recursion-

Function call itself is called recursion.


program-

#lambda function with recursion
func=lambda x: None if x==0 else print(x,end=" ") or func(x-1)

print(func(6))

print(func(7))
print(func(5))
print(func(1))
print(func(3))

output-

6 5 4 3 2 1 None
7 6 5 4 3 2 1 None
5 4 3 2 1 None
1 None
3 2 1 None

-In this program, we create a lambda function which call itself by func(x-1) and for each value of x it print x then again call func().
-When x become 0 then this function return None otherwise call itself by x-1 value and print that x.
