Python Coding challenge - Day 812| What is the output of the following Python Code?

 

    Code Explanation:

1. Importing the pandas library

import pandas as pd

What it does: Imports the pandas library and gives it the alias pd.

Why: pandas is used for data manipulation and analysis, especially with tables called DataFrames.

2. Creating a DataFrame

df = pd.DataFrame({"x":[1,2,3,4]})

What it does: Creates a DataFrame df with one column x containing [1, 2, 3, 4].

DataFrame looks like this:

x

1

2

3

4

Purpose: Store tabular data for easy analysis.

3. Calculating the sum of column x

sum_val = df["x"].sum()

What it does:

df["x"] selects the column x.

.sum() calculates the sum of all values in that column: 1 + 2 + 3 + 4 = 10.

Result: sum_val = 10

4. Finding the maximum value in column x

max_val = df["x"].max()

What it does:

df["x"] selects the column x.

.max() returns the largest value in that column.

Result: max_val = 4

5. Printing the results

print(sum_val, max_val)

What it does: Prints the sum and the maximum value of the column x.

Output:

10 4
