Learn how to use the map() function to execute a specified function for each item in an iterable. See syntax, parameter values, examples and a try it yourself section.
- Map() with Lambda Expressions
- Modify The String Using Map
- If Statement with Map
We can also use lambda expressionswith map to achieve above result. In this example, we are using map() with lambda expression.
In this example, we are using map() function to modify the string. We can create a map from an iterable in Python. Time complexity: O(n), where n is the number of elements in the input list l. Auxiliary space: O(n)
In the example, the double_even() function doubles even numbers and leaves odd numbers unchanged. The map() function is used to apply this function to each element of the numbers list, and an if statement is used within the function to perform the necessary conditional logic. Time complexity: O(n) Auxiliary complexity:O(n)

The map() function returns a map object, which can be easily converted to lists, tuples, etc. Example: Working of map() def square(n): return n*n numbers = (1, 2, 3, 4)
Learn how to use map() to transform and process iterables without using an explicit for loop. See examples of map() with different kinds of functions, iterables, and functional tools.
Apr 12, 2021 · Learn how to use the Python Map Function to convert, round, or get the length of a list of strings or numbers. See the syntax, examples, and benefits of using the Map Function instead of a for loop.
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.
