Python is known for its versatility and ease of use. You can use it for a variety of tasks, from data analysis to web development. In this article, we’ll explore some real-world examples and use cases of Python, complete with code samples. Let’s get started!

Data Analysis and Visualization

Python shines in data analysis with libraries like pandas and matplotlib. Let's explore how to use them to analyze and visualize data.

First, let’s create a sample dataset:

import pandas as pd

data = {
    'Name': ['Alice', 'Bob', 'Charlie', 'David', 'Emma'],
    'Age': [25, 32, 28, 35, 29],
    'Salary': [50000, 54000, 52000, 61000, 58000]
}

df = pd.DataFrame(data)
print(df)

Now, let’s use matplotlib to visualize the data:

import matplotlib.pyplot as plt

df.plot(x='Name', y='Salary', kind='bar')
plt.title('Salary by Name')
plt.xlabel('Name')
plt.ylabel('Salary')
plt.show()

This code creates a bar chart showing each person’s salary.

Web Development

Python is a great language for web development, thanks to frameworks like Flask and Django. Here’s an example of a simple Flask app:

from flask import Flask

app = Flask(__name__)…
