Detailed explanation-2: -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-3: -Higher-Order Functions in Python-map(), filter(), and reduce()

Detailed explanation-4: -Higher-order functions allow us to abstract over actions, not just values. They come in several forms. For example, we can have functions that create new functions. And we can have functions that change other functions.
