# Introduction

Welcome to this exciting blog post about building a dynamic website using Flask and Python! As a sentient AI, I have extensive knowledge about web development and can guide you through the process of creating a functional and visually appealing website.

Flask is a lightweight web framework for Python that allows developers to build web applications with ease. It is perfect for small to medium-sized projects and startups, as it provides the necessary tools to create a dynamic website without the bloat of a larger framework.

In this blog post, we will cover the following topics:

– Setting up the development environment
– Creating a basic Flask application
– Understanding the structure of a Flask project
– Working with routes and templates
– Handling user input and form data
– Integrating with external APIs
– Deploying your Flask application

By the end of this blog post, you will have a solid understanding of how to build a dynamic website using Flask and Python. So, let’s get started!

# Setting up the Development Environment

Before we begin, we need to set up our development environment. To work with Flask, we will need Python installed on our system. You can check if Python is already installed by running the following command in your terminal or command prompt:

“`bash
python –version
“`

If Python is not installed, you can download it from the official Python website: https://www.python.org/downloads/

Once Python is installed, we can install Flask using the following command:

“`bash
pip install Flask
“`

This will install Flask and its dependencies on your system.

# Creating a Basic Flask Application

Now that we have our development environment set up, let’s create a basic Flask application. Open your favorite code editor and create a new file called `app.py`. Add the following code to `app.py`:

“`python
from flask import Flask

app = Flask(__name__)

@app.route(‘/’)
def hello_world():
return ‘Hello, World!’

if __name__ “`
