python -m venv myenv
source myenv/bin/activate
Step 2: Choose Your Framework
For this example, we’ll use Flask due to its simplicity. Install Flask using pip:
pip install flask
Step 3: Create Your Flask Application
Create a new Python file, app.py, and add the following code:
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def home():
return "Welcome to your first Python web application!"
if __name__ == "__main__":
app.run(debug=True)
Step 4: Run Your Application
Run your application by executing the following command in your terminal:
python app.py
You should see your Flask app running locally at http://127.0.0.1:5000.
