Flask: Develop Web Applications in Python

The complete implementation of the problem is provided below. Let's take a look at it!
# Solution

"""Flask Application for Paws Rescue Center."""
from flask import Flask, render_template, abort
app = Flask(__name__)

"""Information regarding the Pets in the System."""
pets = [
            {"id": 1, "name": "Nelly", "age": "5 weeks", "bio": "I am a tiny kitten rescued by the good people at Paws Rescue Center. I love squeaky toys and cuddles."},
            {"id": 2, "name": "Yuki", "age": "8 months", "bio": "I am a handsome gentle-cat. I like to dress up in bow ties."},
            {"id": 3, "name": "Basker", "age": "1 year", "bio": "I love barking. But, I love my friends more."},
            {"id": 4, "name": "Mr. Furrkins", "age": "5 years", "bio": "Probably napping."}, 
        ]

@app.route("/")
def homepage():
    """View function for Home Page."""
    return render_template("home.html", pets = pets)


@app.route("/about")
def about():
    """View function for About Page."""
    return render_template("about.html")

@app.route("/details/<int:pet_id>")
def pet_details(pet_id):
    """View function for Showing Details of Each Pet.""" 
    pet = next((pet for pet in pets if pet["id"] == pet_id), None) 
    if pet is None: 
        abort(404, description="No Pet was Found with the given ID")
    return render_template("details.html", pet = pet)

if __name__ == "__main__":
    app.run(debug=True, host="0.0.0.0", port=3000)

# Explanation
Let's take a look at how we solved this challenge.

## Modifications in `base.html`
Inside the parent template:
1. We added all the redundant tags and imports in this template, such as the `<html>`, `<head>`, and `<body>` tags. Moreover, we imported the `style.css` file that is used by all child templates. 
2. We have used the following three **blocks** as **placeholders** in this template:
   - The `title` block
   - The `heading` block
   - The `content` block
## Modifications in `home.html`,  `about.html` and `details.html`
In the child templates, we just replaced the ***contents*** in their respective **blocks**. 

You might notice that we did not use the `heading` block in `details.html`. The reason is that the order of that heading did not match the order we defined in the template. 

> 📌 **Note that:** It is not necessary to replace all ***placeholder blocks***.

In this lesson, we will discuss how to solve the challenge that was presented in the previous lesson.
