Python Coding challenge - Day 351| What is the output of the following Python Code?

 

Code Explanation:

import matplotlib.pyplot as plt  

plt.hist([1, 1, 2, 3, 3, 3])  

plt.show()

import matplotlib.pyplot as plt:

This imports the matplotlib.pyplot module and gives it the alias plt. matplotlib.pyplot is a commonly used library in Python for creating visualizations such as line plots, bar charts, histograms, etc. In this case, we are using it to create a histogram.

plt.hist([1, 1, 2, 3, 3, 3]):

This line creates a histogram of the data passed to the hist() function. Here's what happens:

plt.hist() is a function that creates a histogram, which is a type of graph used to represent the distribution of a set of data.

The input [1, 1, 2, 3, 3, 3] is a list of values. A histogram represents the frequency of each value in the dataset.

In this case, the data contains the following values:

1 appears 2 times

2 appears 1 time

3 appears 3 times

The histogram will group these values into "bins" and show how many values fall into each bin. By default, plt.hist() will automatically choose the number of bins, but you can also specify this manually if needed.

plt.show():

This line displays the plot on the screen. plt.show() renders the visualization (the histogram, in this case) and opens it in a window so you can view it.

What happens when this code runs:

The hist() function will create a histogram where the x-axis represents the unique values in the dataset (1, 2, and 3), and the y-axis represents how many times each value appears (the frequency).

The value 1 will have a bar at height 2 (because it appears twice).

The value 2 will have a bar at height 1 (because it appears once).

The value 3 will have a bar at height 3 (because it appears three times).

After the histogram is created, plt.show() will display the plot on the screen.

Output:

The output will be a histogram that looks something like this (the exact appearance may vary depending on settings):

X-axis: 1, 2, and 3

Y-axis: Frequencies 2, 1, and 3

This histogram visually represents the distribution of the values in the list [1, 1, 2, 3, 3, 3].
