Python Coding challenge - Day 354| What is the output of the following Python Code?

 

Code

import time  

start = time.time()  

time.sleep(1)  

print(round(time.time() - start))

Explanation

1. Importing the time module

import time

The time module provides various functions to work with time in Python.

It includes features to measure the current time, calculate durations, and pause program execution.

2. Capturing the start time

start = time.time()

The time.time() function returns the current time in seconds as a floating-point number.

The number represents the Unix timestamp, which is the number of seconds since January 1, 1970 (known as the epoch).

This is used to record the starting point of the program execution.

3. Pausing the program for 1 second

time.sleep(1)

The time.sleep() function pauses the execution of the program for a specified amount of time, given in seconds.

Here, time.sleep(1) tells the program to wait for 1 second before proceeding to the next line.

4. Calculating the elapsed time

time.time() - start

The time.time() function is called again to get the current time (after the pause).

The difference between the current time and the recorded start time gives the elapsed time.

For example:

Start time: 1674821371.123

Current time: 1674821372.123

Elapsed time: 1674821372.123 - 1674821371.123 = 1.0

5. Rounding the elapsed time

round(time.time() - start)

The round() function rounds the result to the nearest integer.

Since the pause is for exactly 1 second, the elapsed time will be approximately 1.0, and rounding it gives 1.

6. Printing the result

print(round(time.time() - start))

This line prints the rounded elapsed time to the console.

Since the program pauses for 1 second, the output will be:
