Projects and Applications for Learning Python Online

Key Projects

• Web Scraping Tool: Build a Python application that scrapes data from websites and stores it in a CSV file.
• Personal Expense Tracker: Create a simple program to track expenses, using Python dictionaries to store data.
• Basic Web App: Use Flask to create a basic web application that displays user input on a webpage.
• Data Visualization Project: Utilize libraries like Matplotlib or Seaborn to create visualizations from datasets.

Python Code Examples

Web Scraping Tool Example

            
import requests
from bs4 import BeautifulSoup
import csv

url = 'https://example.com'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

data = []
for item in soup.select('.item-class'):
    title = item.get_text()
    data.append([title])

with open('data.csv', 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerows(data)
            
        

Personal Expense Tracker Example

            
expenses = {}

def add_expense(category, amount):
    if category in expenses:
        expenses[category] += amount
    else:
        expenses[category] = amount

add_expense('Food', 30)
add_expense('Transport', 15)

print("Expenses:", expenses)
            
        

Basic Web App Example with Flask

            
from flask import Flask, request

app = Flask(__name__)

@app.route('/')
def home():
    return '
Welcome to the Expense Tracker
'

@app.route('/submit', methods=['POST'])
def submit():
    user_data = request.form['data']
    return f'
You entered: {user_data}
'

if __name__ == '__main__':
    app.run(debug=True)
            
        

Data Visualization Example

            
import matplotlib.pyplot as plt

categories = ['Food', 'Transport', 'Utilities']
values = [300, 150, 100]

plt.bar(categories, values)
plt.title('Monthly Expenses')
plt.xlabel('Categories')
plt.ylabel('Amount')
plt.show()
