PYTHON-LAMBDA function, map function, filter function

The lambda function mainly understands:

Lambda parameter: Action (parameter). In a lambda statement, the colon is preceded by a parameter, which can have multiple, separated by commas, and a return value to the right of the colon. A lambda statement is actually built as a function object

Map function:

Map (function_to_apply, list_of_inputs). The map function can then enter the objects in the list_of_inputs into the function_to_apply in sequence.

Filter function:

Filter (function_to_apply, list_of_inputs). The filter function is to enter each object in the list_of_inputs into Function_to_apply, and when the return value of Function_to_apply is true, this parameter is preserved.

Otherwise, discard.
