Python Coding challenge - Day 261 | What is the output of the following Python Code?

 

Step-by-Step Explanation

1. Lambda Function Definition

double = lambda x: x * 2

lambda: This is used to create an anonymous (inline) function in Python.

lambda x: x * 2:

This creates a function that takes a single argument x and returns x * 2.

Essentially, this is equivalent to defining a standard function like this:

def double(x):

    return x * 2

double =: The lambda function is assigned to the variable double.

2. Call the Lambda Function

print(double(4))

Here, the double lambda function is called with x = 4.

Computation: 

4×2=8

3. Output

The computed value 8 is then passed to the print() function and displayed.

Final Output

The program will print:

8
