Python Coding challenge - Day 670| What is the output of the following Python Code?

 

Code Explanation:

Importing Pandas

import pandas as pd

Purpose: This imports the Pandas library and gives it the short alias pd (common convention in Python).

Why: Pandas is used for data manipulation; in this case, we’ll use its Series data structure.

Creating a Pandas Series

s = pd.Series([5, 8, 12, 18, 22])

What it does: Creates a one-dimensional Pandas Series containing the values 5, 8, 12, 18, and 22.

Internally: It’s like a list but with extra features, including an index for each value.

Conditional Filtering & Updating

s[s < 10] *= 2

Step 1 — Condition: s < 10

Produces a Boolean mask: [True, True, False, False, False]

Meaning: The first two elements (5 and 8) meet the condition.

Step 2 — Selection: s[s < 10]

Selects only the values [5, 8].

Step 3 — Multiplication Assignment: *= 2

Doubles those selected values in place: [5 → 10, 8 → 16].

Resulting Series:

0    10

1    16

2    12

3    18

4    22

dtype: int64

Calculating the Sum

print(s.sum())

.sum(): Adds up all values in the Series.

Calculation: 10 + 16 + 12 + 18 + 22 = 78

Output:

78

Final Output: 78
