Python Coding challenge - Day 339| What is the output of the following Python Code?

 

Explanation:

import matplotlib.pyplot as plt

This imports the pyplot module from the matplotlib library and aliases it as plt.

Matplotlib is a Python library used for creating static, animated, and interactive visualizations.

pyplot: A module in matplotlib that provides a simple interface for creating plots (like bar charts, line plots, scatter plots, etc.).

x = [1, 2, 3]

This is a list representing the x-coordinates or the positions of the bars on the x-axis.

y = [4, 5, 6]

This is a list representing the heights of the bars. Each value in y corresponds to the height of the bar positioned at the respective x coordinate.

plt.bar(x, y)

This creates a bar chart using the data provided in x and y.

x: Specifies the positions of the bars (categories or values on the x-axis).

y: Specifies the height of each bar.

In this example:

A bar of height 4 is drawn at position 1 on the x-axis.

A bar of height 5 is drawn at position 2 on the x-axis.

A bar of height 6 is drawn at position 3 on the x-axis.

plt.show()

This displays the plot in a separate window or inline (if using Jupyter Notebook).

Without plt.show(), the chart is not rendered or displayed to the user.

Output:

A bar chart.
