This article mainly introduces the statistical project in the total number of code in the Python script sharing, this article directly gives the implementation code, the need for friends can refer to the following Recently you need to count the total number of lines of code in your project, write a Python applet, and have to say how concise Python is, if you wri

the source space (for example, the IDE will display additional information, such as the project tree, class level, etc.), so long lines are difficult to read.Maximum method Length (max.)Check the length of the method and the constructor.Explanation: If a method becomes very long, it will be difficult to understand. Therefore, an excessive approach should usually be made to form several smaller independent methods, each focusing on

　　The requirements are simple: Suppose there is a user table, there are actually 10,000 data in the table, but I do not know how many, I want to fetch 20 data from the database every time, then how to complete it?Programme one:First perform aSelect COUNT (*) as total from user; 　　　　The above SQL statement will detect the total number of records.

In the previous report, a subtotal was generated in the background and then returned to the foreground. Although it was beautiful, it also had defects. For example, if you sorted it, it would be a tragedy! If a non-report is created, some problems may occur. For example, after a t
