Overview In Linux systems, the command line is the main way to perform file and directory operations. Among them, the ls command is the most commonly used and is used to display files and subdirectories in a directory. Although the ls command is convenient, sometimes the output may not be clear and readable. At this point you can see the advantages of the lsd command. lsd is a powerful command, which is the abbreviation of lsDeluxe. LSD is unique in that it provides color output and icon display capabilities. Through different colors and icons, LSD can clearly display the types of files and directories, which allows users to quickly identify file attributes without relying on file extensions and other methods for confirmation. This intuitive display greatly improves the user's operating efficiency. With the traditional ls command

1The basic unit of Unicode computer storage is the byte, which is composed of 8 bits. Since English only consists of 26 letters plus a number of symbols, English characters can be stored directly in bytes. But other languages ​​(such as Chinese, Japanese, Korean, etc.) have to use multiple bytes for encoding due to the large number of characters. With the spread of computer technology, non-Latin character encoding technology continues to develop, but there are still two major limitations: no multi-language support: the encoding scheme of one language cannot be used in another language and there is no unified standard: for example There are many encoding standards in Chinese such as GBK, GB2312, GB18030, etc. Since the encoding methods are not unified, developers need to convert back and forth between different encodings, and many errors will inevitably occur.

What are the similarities and differences between __str__ and __repr__? We all know the representation of strings. Python's built-in function repr() can express objects in the form of strings to facilitate our identification. This is the "string representation". repr() obtains the string representation of an object through the special method __repr__. If __repr__ is not implemented, when we print an instance of a vector to the console, the resulting string may be. >>>classExample:pass>>>print(str(Example()))>>>
