• Text Editor or IDE: Tools like Visual Studio Code, PyCharm, or even Jupyter can be helpful for coding.
• Database: Familiarity with databases like SQLite, PostgreSQL, or MySQL is essential for storing application data.

Getting Started with Your First Python Web Application

Now that you have an overview of the frameworks and tools, let’s walk through a simple example of creating a “Hello World” application using Flask.

Step-by-Step Tutorial: Creating a Flask Application

# Step 1: Install Flask
pip install Flask

# Step 2: Create a simple app
from Flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello, World!"

# Step 3: Run the app
if __name__ == "__main__":
    app.run(debug=True)
        

Now you can run your application and navigate to http://127.0.0.1:5000/ in your browser to see your “Hello, World!” message displayed!
