To build web applications using Python 3, you can use the Flask framework. Flask is lightweight, flexible, and great for creating web apps quickly. Here are the steps to get started:
Install Flask:
First, activate your Python environment and install Flask using pip:
source env/bin/activate # Activate your environment
pip install flask
Create a Simple Flask Application:
Create a Python file (e.g., app.py) and write a basic Flask app:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
return 'Hello, World!'
if __name__ == '__main__':
app.run(debug=True)
Run the Application:
Run your Flask app:
python app.py
Routes and View Functions:
Define routes (URL paths) and view functions (what to display for each route). For example:
@app.route('/about')
def about():
return 'About page'
@app.route('/contact')
def contact():
return 'Contact us'
Dynamic Routes:
Create dynamic routes that accept parameters (e.g., user IDs):
@app.route('/user/<int:user_id>')
def user_profile(user_id):
return f'User {user_id} profile'
Debugging:
Enable debug mode during development for helpful error messages:
app.run(debug=True)
Remember to adapt this example to your specific project.
