High-Order Functions
A high-order function in programming is a function that can either take other functions as arguments or return a function as its result, or both. This concept is closely related to first-class functions, which are treated like any other variable in a language (can be stored in a variable, passed as an argument to a function, or used in control statements). High-order functions are a key feature in functional programming, enabling more abstract or general-purpose code, facilitating code reuse, and making it easier to manipulate functions or data.
A classic example of a high-order function is the map function in Python. This function takes two arguments: a function and an iterable (like a list). It applies the given function to each item of the iterable and returns a map object (which can be easily converted into a list or another iterable type).
In this example:
squareis a simple function that squares its input.mapis the high-order function that takes square and a list of numbers as arguments.- The result is each number in the list numbers squared.
Tarea
Suppose you have a list of temperatures in Celsius, and you want to convert all of them to Fahrenheit. The goal will be to apply a custom transformation to each element in the list using map.
- Create a list of numeric values representing temperatures in Celsius.
- Define a function that converts a temperature from Celsius to Fahrenheit.
- Apply the custom function to each element in the list using
map. - Convert the result from
mapinto a list and print it to see the converted temperatures.
