Detailed explanation-1: -o Functions that take other functions as arguments or return functions as results are called higher-order functions. o Higher-order list functions like map, filter, and reduce capture common list-manipulation patterns. They are much simpler than loops for performing many list manipulation tasks.

Detailed explanation-2: -In functional programming, filter is a higher-order function that processes a data structure (usually a list) in some order to produce a new data structure containing exactly those elements of the original data structure for which a given predicate returns the boolean value true .

Detailed explanation-3: -Python’s filter() is a built-in function that allows you to process an iterable and extract those items that satisfy a given condition. This process is commonly known as a filtering operation.

Detailed explanation-4: -map. The map() method creates a new array by calling the callback function provided as an argument on every element in the input array. The map() method will take every returned value from the callback function and creates a new array using those values.
