map function: Prototype: Map (function, sequence), which is to map a list to another list, How to use: def f (x): Return x**2 L = Range (1,10) Map (f,l) OUT[3]: [1, 4, 9, +, BA] reduce function Prototypes: Reduce (function, sequence, startvalue), which is to generalize a list into one output,How to use: def f2 (x,y):

Python built-in function map/reduce/filter These three functions are handy, very cool.filter () function: The filter function is equivalent to filtering, calling a Bool_func (a method that returns only bool type data) to iterate through the elements in each sequence.
