Day Twenty Two: Becoming a Developer

Congratulations on making it to day twenty two of your journey to becoming a developer! Today, we will be focusing on templates, HTML forms, and making requests in Flask. Let’s dive in!

Templates

Templates are a great way to create reusable and dynamic content in your web applications. In Flask, you can use Jinja templating to render HTML templates. Here’s an example of how to use a template in Flask:


from flask import Flask, render_template

@app.route('/')
def index():
return render_template('index.html')


HTML Forms

HTML forms allow users to input data and send it to the server. You can create a form in HTML using the <form> tag. Here’s an example of a simple form:


<form action="/submit" method="POST">
<input type="text" name="username">
<input type="submit" value="Submit">
</form>


Requests in Flask

In Flask, you can handle requests using decorators. The @app.route() decorator allows you to define routes for your web application. Here’s an example of how to handle a POST request in Flask:


from flask import Flask, request

@app.route('/submit', methods=['POST'])
def submit_form():
username = request.form['username']
return f'Hello, {username}! Your form has been submitted.'


Keep practicing and learning, and you’ll be well on your way to becoming a developer. Good luck!
