Python can be seamlessly integrated with popular frontend technologies such as HTML, CSS, and JavaScript. This allows developers to create dynamic and interactive web applications by combining the strengths of Python on the backend with frontend frameworks like React, Angular, or Vue.js.
Install Flask: First, you need to install Flask if you haven’t already. You can do this using pip, Python’s package manager:
pip install Flask
Create the Flask Application: Create a new Python file named app.py
and add the following code:
from flask import Flask
# Create a Flask application
app = Flask(__name__)
# Define a route for the homepage
@app.route('/')
def hello_world():
return 'Hello, World!'
# Run the Flask application
if __name__ == '__main__':
app.run(debug=True)
Run the Flask Application:Open a terminal or command prompt, navigate to the directory where app.py
is located, and run the following command:
python app.py
View the Web Application:
Open your web browser and navigate to http://localhost:5000/. You should see a "Hello, World!" message displayed on the webpage.
