Ah, it's hard to say a word, so I will not talk about it anymore. Background: At present, there are many bug management tools on the market, but each has its own characteristics. The most famous one is Zen road. After learning tornado, I accidentally came into

The example in this article describes how Python obtains the system default character encoding. Share to everyone for your reference. The specific analysis is as follows: In Python code, the normal string is encoded in the same way as the program source file, and many Ides save the program source file by default as the system's default character encoding. Here

This article describes how to use exception handling in Python to determine the operating system platform method. this method is novel and can be used as a reference by anyone who needs it. Code example: The code is as follows: Try:Import termios, TERMIOS 1Failed T ImportError:Try:Import msvcrt 2Failed T ImportError:Try:From EasyDialogs import AskPassword 3Failed T ImportError:Getpass = "default_getpass" 4

There is a platform module in Python to obtain information about the operating system.Import platformPlatform. machine () # Returns the machine type, e.g. 'i386' Platform. node () # Returns the computer's network name Platform. platform (aliased = 0, terse = 0) # Returns a single string identifying the underlying platform Platform. processor () # Returns the (true) processor name Platform. python_branch () # Returns a string identifying the

Objective Every operational officer should be aware of the configuration of the machine he is managing, because it is very helpful for us to deal with the problem quickly, for example, as the business grows, suddenly some machines load up badly, at this time to troubleshoot reasons, in addition to from the application, architecture analysis, the current hardware performance analysis should be an essential link, Today we will not use the third party module, with the
