Last week's progress: multi-process Learning
Practice today
The initially designed interface performance stress test code is as follows:
1 #!
We often get the current date submitted by a user. Based on this date, we need to return the date of the previous day, the next day, or the conversion operation. Using Python can easily solve these date computing problems anytime and anywhere. As
This article mainly introduces how to implement multi-thread crawling by using python to count the ratio of men and women in the BBS in the school. If you are interested, refer to the article I will continue to learn.

Python supports multiple threads through the thread module, and the syntax is concise. Now let's look at the multithreading in Python through an example:
Import threadimport time # ensure that only one additional thread is started isrunning = false #
To obtain time-related information, you need to use the python time module. The Python time module provides many useful functions. You can go to the official documentation to learn about the current time, to obtain the timestamp of the current time,
Conversion of python timestamps and formatting time, and conversion of python formattingIn python, time-related modules are mainlyTimeAndDatetime
If you want to obtain the current system timestamp: time. time (), it is a float data type.
Obtain the
Python time processing and python Processing
In practice, if you encounter a time processing problem, you need to compare Sep 06,201 4 (UTC time) with the current time sooner or later to know the operation of the time in the format. Therefore, when
Well, the question is very simple, but some details are quite interesting.
The question is: Determine whether this year is a leap year. If the condition of a leap year is met, the year model 400 is 0, or the model 4 is 0, but the model 100 is not 0.
Python embedded time template translation and description
I. Introduction
The time module provides functions for various operation times.Note: There are two methods to indicate time:The first method is the timestamp (offset calculated in seconds
How to use the time () method in Python
This article describes how to use the time () method in Python. It is the basic knowledge of getting started with Python. For more information, see
The return time of the time () method, expressed in seconds
MySQL supports two main table storage formats: MyISAM and InnoDB. InnoDB was used for a project last month. The results are very slow and only a dozen pieces can be inserted in one second. Later I changed to MyISAM format and inserted tens of
This article mainly introduces two examples of how to use Python to obtain information about the windowns system, such as CPU, memory, and hard disk. the pythonwmi module can be used as a reference.
Example 1:
Python uses the WMI module to obtain
This article mainly introduces the code for parsing the crontab configuration file implemented by python. It can also be called the crontab of python. the code contains a large number of comments. For more information, see

This article mainly introduces how to get the current time in Python. if you need it, you can refer to the time when I sometimes write a program to use the current time. I want to use python to get the current time, although it is not very difficult,
Python reads files and timesys modules. the usage of some standard library functions is also to be learned, such as osresetsstringqueuesocket #! Usrbinpythonprintord (a) printchr (97) # Convert the characters and integers into fpopen (& amp; quot;
