Create Python Module

Now we need to create our module where we will import all of our functions from.

Essentially, you are just creating your functions in a separate .py file, so we do not cluttermain.py.

It must be in the same folder.

We will integrate them LATER - in the INTEGRATION step!

The following is an example of the pokedex.py module.

pokedex.py

import requests # Must import requests so we can use API

# API Base URL for PokéAPI
API_URL = "https://pokeapi.co/api/v2/pokemon/"

# Dictionary to store collected Pokémon
pokedex = {}

def search_pokemon(name):
    """Search for a Pokémon by name or ID and return its details.""" # Triple quotes is a docstring - allows multiline comments!
    response = requests.get(f"{API_URL}{name.lower()}")
    if response.status_code == 200:
        data = response.json()
        return {
            "name": data["name"].capitalize(),
            "id": data["id"],
            "height": data["height"],
            "weight": data["weight"],
            "types": [t["type"]["name"] for t in data["types"]]
        }
    else:
        print("Pokémon not found.")
        return None

def add_pokemon(name):
    """Add a Pokémon to the Pokédex."""
    pokemon = search_pokemon(name)
    if pokemon:
        pokedex[pokemon["name"]] = pokemon
        print(f"{pokemon['name']} added to Pokédex.")

def view_pokedex():
    """Display all collected Pokémon."""
    if pokedex:
        for name, details in pokedex.items():
            print(f"{name} - ID: {details['id']}, Height: {details['height']}, Weight: {details['weight']}, Types: {', '.join(details['types'])}")
    else:
        print("Your Pokédex is empty.")

def remove_pokemon(name):
    """Remove a Pokémon from the Pokédex."""
    if name.capitalize() in pokedex:
        del pokedex[name.capitalize()]
        print(f"{name.capitalize()} removed from Pokédex.")
    else:
        print("Pokémon not found in your Pokédex.")

#<------------------------------TEST YOUR FUNCTIONS BELOW------------------------------>

---

Now, with the above we have defined all functions and included the API call. Keep in mind some APIs such as WeatherAPI will require a key as well - a separate example will be provided.

However, we now need to test each function. Rather than having to test each in the UI and spend forever, it's often best to just run the functions below our code here.

Here is an example of how you might test each function:

#<------------------------------TEST YOUR FUNCTIONS BELOW------------------------------>
print(search_pokemon('Pikachu'))

As the search_pokemon() function only returns a value and does not print if it is successful, we need to add the print statement to the function call to see what values it actually returns

---

#<------------------------------TEST YOUR FUNCTIONS BELOW------------------------------>
add_pokemon('Pikachu')

This function actually has print statements, so we can test it just as above

---

#<------------------------------TEST YOUR FUNCTIONS BELOW------------------------------>
add_pokemon('Pikachu')
view_pokedex()
remove_pokemon('Pikachu')

Some functions may depend on other functions being run first. For instance, we cannto view a pokemon in our pokedex or remove it unless we add one first.

---

#<------------------------------TEST YOUR FUNCTIONS BELOW------------------------------>
view_pokedex()
remove_pokemon('Pikachu')

In saying that, we still need to test both on their own so we know that all possible outcomes will work.
