Dec 03, 2016 am 10:50 AM

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.

Python: compiler or Interpreter?Python: compiler or Interpreter?May 13, 2025 am 12:10 AM

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
