How can I use Flask to build a web application?

Flask is a micro web framework for Python. You can start by installing Flask and creating a simple app.

What are the basic steps to set up a Flask app?

First, install Flask using pip. Then, create a Python file, import Flask, and define your app and routes.

Can you show me a simple code example?

Sure! Here's a basic example:

from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return 'Hello, Flask!'

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

How do I run this Flask app?

You can run the app by executing the Python file in your terminal. Use python yourfile.py.
