cmp python

In Python basic programming, there's an advanced sort of:"If you want elements to be sorted in a particular way, rather than the sort function by default, in ascending order of elements according to Python's default collation, which is explained in

In this article, let's look at the built-in functions in the Python dictionary, which I'll What are the CMP in PythonFor instructions, and pythoncmp ()method to parse. Well, don't say much, let's get into the article. Describe The CMP () function

Analysis of the cmp comparison principle of Python built-in comparison functions Cmp (x, y): compares two objects. if the former is smaller than the latter,-1 is returned. if the former is equal, 0 is returned. if the former is greater than the

This article mainly introduces the python2.x version of the CMP () method of using the tutorial, in the python3.x version of the method is no longer built in, the need for friends can refer to the The CMP () method returns a symbol of the

Comparison principle of CMP comparison function in Python CMP (x, y): Compares 2 objects, which are less than the latter return-1, and equal returns 0, greater than the latter returning 1. Comparison principle of CMP comparison function in Python

CMP (x, y): Compares 2 objects, which are less than the latter return-1, and equal returns 0, greater than the latter returning 1. Comparison principle of CMP comparison function in Python The CMP functions of Python can be compared between the same

DescribeThe CMP (x, y) function is used to compare 2 objects if x y returns 1.GrammarThe following is the syntax for the CMP () method:CMP (x, y)ParametersX--Numeric expression.Y--numeric expression.return valueIf x y returns 1.InstanceThe

Python development [Notes]: sort Sorting Algorithm (cmp, key, reverse), pythoncmpSort The sorting function is often used in the program. Python provides the sort and sorted functions, one in-situ sorting and one Returning New results after sorting. 1

Python function-cmp (x, y) today I will share a very useful and simple function named cmp in python. as you may have guessed in spelling, this is a comparison function, yes, it only returns three values, positive, 0, and negative. let's take a look:
