Python Coding challenge - Day 427| What is the output of the following Python Code?

 

Code Explanation:

1. Importing Libraries

from scipy import stats

import numpy as np

numpy is used for creating and manipulating arrays.

scipy.stats provides statistical functions — like mean, median, and mode.

2. Defining Data

data = np.array([1, 2, 2, 3, 4, 4, 4, 5])

This is your sample data array. It contains repeated values. Let’s look at the frequencies:

Value Frequency

1 1

2 2

3 1

4 3 

5 1

3. Calculating Mode

mode = stats.mode(data, keepdims=True)

stats.mode() returns the most frequent value in the array (i.e., the mode).

keepdims=True keeps the output in the same dimensional structure (as an array).

As seen above, 4 appears most frequently (3 times), so the mode is 4.

The mode object is a ModeResult, which has:

.mode → the value(s) that appear most frequently

.count → the count(s) of how often the mode appears

4. Printing the Mode

print(mode.mode)

Final Output:

[4]

Because keepdims=True, the result is still a NumPy array — hence [4] instead of just 4.
