1. os package
The os package includes a variety of functions to implement many functions of the operating system. This package is very complex. Some commands of the os package are used for file management. We list the most commonly used ones here:
mkdir(path) creates a new directory, path is a string, indicating the path of the new directory. Equivalent to the $mkdir command
rmdir(path) deletes an empty directory. path is a string indicating the path of the directory you want to delete. Equivalent to the $rmdir command
listdir(path) returns all files in the directory. Equivalent to the $ls command.
remove(path) deletes the file pointed to by path.
rename(src, dst) Rename the file, src and dst are two paths, indicating the paths before and after renaming respectively.
chmod(path, mode) changes the permissions of the file pointed to by path. Equivalent to the $chmod command.
chown(path, uid, gid) changes the owner and ownership group of the file pointed to by path. Equivalent to the $chown command.
stat(path) View additional information about the file pointed to by path, equivalent to the $ls -l command.
symlink(src, dst) creates a soft link for the file dst, src is the path of the soft link file. Equivalent to the $ln -s command.
getcwd() queries the current working path (cwd, current working directory), which is equivalent to the $pwd command.
2. shutdown package
copy(src, dst) copies files from src to dst. Equivalent to the $cp command.
move(src, dst) moves files from src to dst. Equivalent to the $mv command.

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

This article explains how to use Beautiful Soup, a Python library, to parse HTML. It details common methods like find(), find_all(), select(), and get_text() for data extraction, handling of diverse HTML structures and errors, and alternatives (Sel

Python, a favorite for data science and processing, offers a rich ecosystem for high-performance computing. However, parallel programming in Python presents unique challenges. This tutorial explores these challenges, focusing on the Global Interprete

This tutorial demonstrates creating a custom pipeline data structure in Python 3, leveraging classes and operator overloading for enhanced functionality. The pipeline's flexibility lies in its ability to apply a series of functions to a data set, ge

Serialization and deserialization of Python objects are key aspects of any non-trivial program. If you save something to a Python file, you do object serialization and deserialization if you read the configuration file, or if you respond to an HTTP request. In a sense, serialization and deserialization are the most boring things in the world. Who cares about all these formats and protocols? You want to persist or stream some Python objects and retrieve them in full at a later time. This is a great way to see the world on a conceptual level. However, on a practical level, the serialization scheme, format or protocol you choose may determine the speed, security, freedom of maintenance status, and other aspects of the program

Python's statistics module provides powerful data statistical analysis capabilities to help us quickly understand the overall characteristics of data, such as biostatistics and business analysis. Instead of looking at data points one by one, just look at statistics such as mean or variance to discover trends and features in the original data that may be ignored, and compare large datasets more easily and effectively. This tutorial will explain how to calculate the mean and measure the degree of dispersion of the dataset. Unless otherwise stated, all functions in this module support the calculation of the mean() function instead of simply summing the average. Floating point numbers can also be used. import random import statistics from fracti
