Python Coding challenge - Day 742| What is the output of the following Python Code?

 

Code Explanation:

1. Importing the statistics library

import statistics

The statistics module in Python provides functions for mathematical statistics like mean, median, mode, stdev, etc.

We import it here to calculate mean, median, and mode of the dataset.

2. Creating the dataset

data = [10, 20, 20, 30, 40]

A list named data is created with values: [10, 20, 20, 30, 40].

This dataset contains repeated values (20 appears twice).

3. Calculating the mean

mean = statistics.mean(data)

4. Calculating the median

median = statistics.median(data)

statistics.median(data) returns the middle value when data is sorted.

Sorted data = [10, 20, 20, 30, 40]

Middle element = 20

So, median = 20.

5. Calculating the mode

mode = statistics.mode(data)

statistics.mode(data) returns the most frequently occurring value in the dataset.

Here, 20 appears twice, more than any other number.

So, mode = 20.

6. Printing results

print(mean, median, mode)

This prints the values:

24 20 20

Final Output:

24 20 20
