Python Coding Challenge - Question with Answer (ID -300626)

 

Explanation:

Code 

print(5 or 10)

Purpose of the Code

This code uses the or operator and prints the value returned by it.

Understanding the or Operator

or is a logical operator.

It checks the values from left to right.

If the first value is truthy, it returns that value.

Otherwise, it returns the second value.

Syntax:

A or B

Evaluating the Expression

Expression:

5 or 10

5 is a non-zero number.

Non-zero numbers are truthy in Python.

Since 5 is truthy, Python immediately returns 5.

Python does not check 10.

Short-Circuit Evaluation

Python stops evaluating as soon as it finds the first truthy value.

Here:

5 or 10

Python stops at 5 and returns:

5

6. Role of print()

The print() function displays the returned value on the screen.

It becomes:

print(5)

Output

5
