Think of a function as a super-cool gadget that can do a special job for you, just like a robot helper!

Let's create a gadget called "my_function":

def my_function(): # Inside the gadget, we write the instructions for its job:
     print("👋 Hello from Pykid!")

Now, we can use the gadget by calling its name, like pressing a button:

my_function() # This makes the gadget do its job, and we see the message! 
# Output: 👋 Hello from PyKid!

We can make our gadgets even more awesome by giving them special tools to work with!

For example, let's give a gadget a name to use in a greeting:

def greet_friend(name): # Now the gadget knows to use the name we give it: 
     print(f" Hello, {name}! How are you today?")

Let's try it out!

greet_friend("Aisha") 
# Output: Hello, Aisha! How are you today? 
greet_friend("Anas") 
# Output: Hello, Anas! How are you today?

Cool, right? The gadget can do different things depending on the tools we give it! It's like having a whole toolbox of gadgets!

Remember, functions are like our trusty robot helpers in coding, making our programs easier and more fun to build!

Creating a Function to Introduce Animals:

• Imagine a special machine called "animal_sounds" that knows about different animals and their sounds.

• This machine takes the name of an animal as its input.

• It has a set of instructions for each animal it knows:

  • If you tell it "cat", it prints " A cat says: Meow!"

  • If you tell it "dog", it prints " A dog says: Woof!"

  • And so on for cows, ducks, and more!

• If you give it an animal it doesn't know, it politely says "Sorry, I don't know that animal!"

•   def animal_sounds(animal):
        if animal == 'cat':
            print("🐱 A cat says: Meow!")
        elif animal == 'dog':
            print("🐶 A dog says: Woof!")
        elif animal == 'cow':
            print("🐮 A cow says: Moo!")
        elif animal == 'duck':
            print("🦆 A duck says: Quack!")
        else:
            print("Sorry, I don't know that animal!")
  
    # Introducing different animals and their sounds
    animal_sounds('cat')
    # Output: 🐱 A cat says: Meow!
  
    animal_sounds('dog')
    # Output: 🐶 A dog says: Woof!
  
    animal_sounds('cow')
    # Output: 🐮 A cow says: Moo!
  
    animal_sounds('duck')
    # Output: 🦆 A duck says: Quack!
  
    animal_sounds('elephant')
    # Output: Sorry, I don't know that animal!
  

  Playing Animal Sounds:

  • We can make this machine even cooler by giving it the ability to play actual animal sounds!

  • We import a special tool called "playsound" that can play audio files.

  • Now, instead of just printing the sound, the machine can play it out loud!

  • We provide the paths to the animal sound files, like a map for the machine to find the right sounds.

Calling the Function:

• To use the machine, we call it by its name, "animal_sounds", and give it the name of the animal we want to hear.

• For example, "animal_sounds('cat')" will make it play the cat's meow.

• We can call it multiple times to hear different animals!

from playsound import playsound

# Function to play animal sounds
def animal_sounds(animal):
    if animal == 'cat':
        playsound('https://www.myinstants.com/media/sounds/meow_3.mp3')  
    elif animal == 'dog':
        playsound('https://www.myinstants.com/media/sounds/dog-barking-sound-effect.mp3')  
    elif animal == 'cow':
        playsound('https://www.myinstants.com/media/sounds/cow1.mp3')  
    elif animal == 'duck':
        playsound('https://www.myinstants.com/media/sounds/duck.mp3')  
    else:
        print("Sorry, I don't know that animal's sound!")

# Calling the function to play animal sounds
animal_sounds('cat')
animal_sounds('dog')
animal_sounds('duck')
animal_sounds('cow')

Handling Unknown Animals:

animal_sounds('elephant')
# Output: Sorry, I don't know that animal's sound!
