Refer to Region. Regular Expressions (also known as res, RegEx, and RegEx pattens) are small and highly specializedProgramming LanguageIt is embedded in the python development language and can be used through the re module. Regular Expression Pattern can be compiled into a series of bytecode and then executed using the engine written in C. The following describes the regular expression syntax. The regular expression contains a metacharacter list

Mac terminal by default in the opening of a new Tab/window need to re-enter the password ssh, very inconvenient. This article completes the setting in the Mac, realizes the clone session function in the Securecrt/xshell, namely opens a terminal SSH connection without re-entering the password.The principle is very simple, open an SSH connection in the background, and later need to use SSH to the same host, t

The Delphi thread can run synchronously in the main thread by calling Athread.synchronize (Aproc), where Athread will hang until the main thread finishes executing aproc.If there is Bthread, Bthread.synchronize (Bproc) is called, and Athread is released in Bprocprocedure Tbthread.bproc begin athread.terminate; athread.waitfor; Athread.free; End;At this point our program will be stuck, the following code can avoid deadlocks, is a generic thread waiting for the end code. athread.terminate;

1. Summary of the usage of re regular(1), ^ indicates which character to start with eg: ' ^g ' denotes a string starting with G. means that any character ' ^g.d ' represents a second character starting with G, and a third string of B indicates that a character appears any number of timesImport re ' bobby123 ' '^b.*' # Any string that begins with B appears any number of times ^ begins with . Any cha

1. What is an exception(1) The basic idea of the anomaly is to let a function find itself unable to solve the error when throwing an exception, let the caller to solve. Exception handling mechanism is similar to compile-time type checking and ambiguity control at runtime counterpart, it is a non-local control structure, when throwing an exception, we use the stack fallback to find the upper function that can handle the exception. Some people think of an anomaly as a big, irreparable mistake in t

using less time Do not run all your backups at the same time. Do not run a batch program at the same time as a large backup. Use the backup option to write to multiple files. This will scatter your I/O and increase the number of threads. Use several backup technologies at the same time: complete, differentiated, and log. Local recovery From a recovery standpoint, most of the time mentioned above is used for recovery. Here are some additional tips: Different phases are used in different a
