Python Coding challenge - Day 762| What is the output of the following Python Code?

 

Code Explanation:

1. Importing the Library

import statistics

The statistics module in Python provides functions to calculate mathematical statistics (like mean, median, mode, stdev, etc.) for numerical data.

2. Creating the Dataset

data = [2, 4, 4, 6, 8]

A list called data is created with values [2, 4, 4, 6, 8].

This dataset will be used to calculate mean, median, and mode.

3. Calculating the Mean

mean_val = statistics.mean(data)

statistics.mean() calculates the average of the numbers.

Formula: (2 + 4 + 4 + 6 + 8) / 5 = 24 / 5 = 4.8.

So, mean_val = 4.8.

4. Calculating the Median

median_val = statistics.median(data)

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

Sorted data = [2, 4, 4, 6, 8].

The middle element = 4.

So, median_val = 4.

5. Calculating the Mode

mode_val = statistics.mode(data)

statistics.mode() returns the most frequent value in the dataset.

Here, 4 appears twice, while others appear once.

So, mode_val = 4.

6. Printing the Results

print(mean_val, median_val, mode_val)

It prints the values of mean, median, and mode.

Output:

4.8 4 4
