This article mainly introduces the relevant knowledge of "how to achieve command line screen cleaning in different python systems". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to achieve command line screen cleaning in different python systems" can help you solve the problem.

Basic principles

Python has a built-in module called os, which provides functional interface functions for most operating systems, one of which is to execute shell commands. Different operating systems can achieve the screen cleaning effect of the system by executing different screen cleaning commands.

Import os # introduces os module os.system (shell command) # using the system function of os module, you can execute shell command Windows to clear the screen

The screen clearing function of Windows is cls, so the screen cleaning code of Windows is:

Import osos.system ("cls") Mac clear screen

The screen clearing function of Mac is different from that of Windows. Its screen cleaning function is clear, so the screen cleaning code of Mac is:

Import osos.system ("clear") Linux clear screen

There are three screen removal methods for Linux, namely clear,reset and printf "\ 033c", so Linux has the following three screen removal methods:

Import osos.system ("clear") # using clear to clear the screen will refresh the screen, but in essence it just makes the terminal display page turn back one page # if you scroll up, you can also see the previous operation information os.system ("reset") # using the reset command will completely refresh the terminal screen The operation information entered before will be cleared # the command process is a bit slow os.system ('printf "\ 033c") # Real clear the terminal screen, similar to the effect of Windows's cls # Note, the instructions here are enclosed in single quotation marks because the internal instructions use double quotes on "how to achieve command line clearing screen in different python systems".
