If the number of numbers is the same, the maximum number is used. For example, 1 outputs 1,121 output, 1

This article mainly introduces the Python Functional Programming Guide (ii): Starting from the function, this article explains the definition of a function, the use of function assignment, closures, as parameters, and so on, the need for friends can refer to the 2. Start with the function 2.1. Define a function A summation function is defined as follows: The code is as follows: def add (x, y): return

, we can also extend the action to only the case where there are no parameters: The code is as follows: public static func { return x = y = func (x, y); }In this way we have solved the function of converting the normal function into partial application, but the problem is. If we start with a partial application, how do we convert it into a normal function? Naturally we also need the following extension to be able to convert it back: The code is as follows: public static func { return (x, y) = =

http://www.nowamagic.net/librarys/veda/detail/1707 the scope chain and variable objects are described earlier, it is easy to understand the closure now. Closures in fact, everyone has been talking rotten. Still, it's a theory to try to discuss the closure from a theoretical point of view, and see how the closures inside the ECMAScript work.It is still necessary to take a look at some basic definitions of functional

(): print ("before invoked:") func () print ("after invoked:") return wrapper @decoratordef func (): print ("Func invoked:") func ()There is also how to add parameters to decorator and how to modify the contents of the wrapper __name__ property to Func, which is not described here.Seven partial functions (partial function)What is a partial function? A partial function is a function that adds a default parameter to a function. In Python, you can use functools.p

Since it is functional programming, it is naturally unavoidable to know more about the function:Methods are not equal to functions (function)The method is not a function but can be converted into a function, can be converted by hand or automatically converted by the compiler (compiler) in appropriate cases. A reverse conversion is not a function that cannot be converted to a method. Let's take a look at the
