Python Coding challenge - Day 314| What is the output of the following Python Code?

 

Code Explanation:

Lambda Function:

lambda x: x ** 0.5 defines an anonymous function (lambda function) that takes a single argument x.

The body of the function is x ** 0.5, which calculates the square root of x.

In Python, raising a number to the power of 0.5 is equivalent to taking its square root.

Assigning the Function:

sqrt = lambda x: x ** 0.5 assigns the lambda function to the variable sqrt.

Now, sqrt can be used as a regular function to compute square roots.

Calling the Function:

result = sqrt(16) calls the sqrt function with the argument 16.

Inside the function:

16 ** 0.5 is calculated.

The function returns 4.0.

Printing the Result:

print(result) outputs the value of result to the console, which is 4.0.

Output:

The program prints:

4.0

Note:

The result is 4.0 (a float), even though the square root of 16 is 4, because the ** operator with 0.5 produces a floating-point number.

If you want the output as an integer, you can cast the result to an int:

sqrt = lambda x: int(x ** 0.5)

result = sqrt(16)

print(result)

This would print:

4
