Oct 23, 2024 · The map () function is used to apply a given function to every item of an iterable, such as a list or tuple, and returns a map object (which is an iterator). Let’s start with a simple example of using map () to convert a list of strings into a list of integers. Python. s = ['1', '2', '3', '4'] res = map(int, s) print(list(res)) Output. [1, 2, 3, 4]
The map() function executes a specified function for each item in an iterable. The item is sent to the function as a parameter.
Python map () Function. The map() function executes a given function to each element of an iterable (such as lists, tuples, etc.). Example. numbers = [1,2,3,4] # returns the square of a number def square(number): return number * number. # apply square() to each item of the numbers list . squared_numbers = map(square, numbers)
Python’s map() is a built-in function that allows you to process and transform all the items in an iterable without using an explicit for loop, a technique commonly known as mapping. map() is useful when you need to apply a transformation function to each item in an iterable and transform them into a new iterable.

Nov 9, 2021 · The map() function (which is a built-in function in Python) is used to apply a function to each item in an iterable (like a Python list or dictionary). It returns a new iterable (a map object) that you can use in other parts of your code.
The built-in map() function in Python allows you to apply a transformation function to each item of one or more iterables, producing an iterator that yields transformed items. This function is particularly useful for processing and transforming data in a functional programming style without explicitly using a for loop.
The Python map () function is a built-in function that allows us to transform each item from an iterable with the help of a process known as mapping. In this process, the map () function applies a function on every element of the given iterable and returns a new iterable object.
