Passing Ingredients (Parameters)
Just like you’d add ingredients to a smoothie, functions have parameters, which are the data you pass to them. For example, if you have a function called makeSmoothie, you might pass it the parameters strawberry, banana, and spinach.
Returning the Magic (Values)
Once the function has done its magical work, it can return a value, just like when a genie grants your wish. The returned value is like the delicious smoothie you’ve created. It can be a string, a number, or even another function.
Here’s a simple example:
def makeSmoothie(fruit1, fruit2, veggie):
return f"Your smoothie is ready: {fruit1}, {fruit2}, and {veggie}!"
my_smoothie = makeSmoothie("strawberry", "banana", "spinach")
print(my_smoothie)
And boom! Your smoothie is ready, all thanks to the magic of functions. So, next time you need to perform a specific task in your code, don’t conjure up new spells; just call upon the mighty functions!
