This article mainly introduces three methods of running time from the start of the python computing program to the end of the program and the CPU time of the program running. for details, refer to the execution time.
Method 1
The code is as follows:
Import datetimeStarttime = datetime. datetime. now ()# Long runningEndtime = datetime. datetime. now ()Print

When C-free is used, mingw5 is used to compile C ++ code, and the first line of error is returned:

> 1: Error: stray '\ 187' in program
> 1: Error: stray '\ 191' in program

Method 1Copy codeThe Code is as follows:Import datetimeStarttime = datetime. datetime. now ()# Long runningEndtime = datetime. datetime. now ()Print (endtime-starttime). seconds
Method 2Copy codeThe Code is as follows:Start = time. time ()Run_fun ()End = time. time ()Print end-start
Method 3Copy codeThe Code is as follows:Start = time. clock ()Run_fun ()End = time. clock ()Print end-start
Methods 1 and 2 both contain the CPU usage time of other programs, which is the running t
I remember using a program flowchart when writing a document. When it comes to the process, I think it should be a diagram describing what to do first and then what to do. Then I searched the internet and found that the program flow chart is also very exquisite. I have my own rules. Next I will introduce some of the knowledge I should know before drawing the program
Windows beginnersProgramDesign, recently made a small software, the whole process is very messy;
Previously, C was used for speech recognition.AlgorithmThere is a habit of drawing flowcharts. No matter how hard it is to draw a flowchart, there will be a large architecture in mind, and the idea is still clear;
However, the recent learning of MFC is directly messy. I always think about where to write it, and I cannot understand a sequence or framework
In software engineeringProgramFlowcharts are essential. How can we draw program flowcharts? Just like writingArticleSimilarly, if you want to write an article, you must first learn to recognize and write the text. Therefore, if you want to draw a flowchart, you must first understand the symbols in the flowchart.
The standard symbols of the program flowchart
(016) given an ordered array (incrementing), write a program to build a binary tree with the minimum height (keep it up), 016 Binary Tree
Given an ordered array (ascending), write programs construct a binary tree with the minimum height.
Because the array is incremental and ordered, each time a node is created in the middle, the minimum tree is similar to the binary search method.
struct TreeNode{int data;TreeNode* leftChild;TreeNode* rightChild;};vo

A year ago, when I got a PHP program called Twig, was immediately impressed by the author OOP programming ideas, it is difficult to imagine Twig all the functions (calendar, mail, personalization) in a php file (index.php3) executed, This is because the author used the idea of separating the program code from the page frame, but I also see that d

How to develop control panel program (CPL Program)
Cpl program is a kind of deformation of the dynamic link library (DLL), but the extension is. CPL, And the entry function is cplapplet () instead of dllmain (). It is actually very simple to compile.
Create a DLL project and write the following code:

Today finally have time to study a very large project compiled into an EXE and a number of DLLs, the program is the first command to execute it? What rules does the operating system use to find the first instruction that should be executed (or how to find the first entry function)?When we wrote the Windows program before, we wrote a main () function, then wrote our own logic, then compiled, and then click o

As an industry veteran, I don't think it generalize! To look at this problem dialectically, depending on the child's specific situation, specific problems and specific analysis.
