Python standard library and third-party library-Python tutorial

This article mainly introduces the Python standard library and third-party library. For more information, see the following section to describe the Python standard library and third-party library, for your reference:

Tkinter ---- default graphical interface of Python.
Tkinter is a module for the Tk interface. the Tkinter Library provides interfaces for the Tk API, which belongs to the GUI tool group of Tcl/Tk. Tcl/Tk is a writing and graphics device developed by John Ousterhout. Tcl (Tool Command Language) is a macro language used to simplify the development of complex programs in shell. Tk toolkit is developed with Tcl to simplify the design process of user interfaces. The Tk toolkit consists of many different widgets, such as a button and a scroll bar. With these widgets provided by Tk, we can quickly launch a GUI. Perl, Scheme, and other languages also use the Tk library for GUI development. Tkinter is cross-platform and can be used on various platforms.

Python Imaging Library (PIL)-It provides powerful graphic processing capabilities and supports a wide range of graphic file formats. this Library can convert, print, and display graphic formats. It can also process some graphic effects, such as zoom-in, zoom-out, and rotation. It is a powerful tool for user image processing.

Pmw (Python megawidgets) is a super GUI component set-an advanced GUI component built using the Tkinter module. each Pmw combines one or more Tkinter components, to achieve more useful and complex functions.

PyXML-a toolkit for parsing and processing XML documents using Python. the 4DOM in the package is fully compatible with W3C DOM specifications. It contains the following content:
Xmlproc: a compliant XML parser.

Expat: a fast, non-verified XML parser. There are other
At the same level as him, there is also PyHtml PySGML.

PyGame-a module used for multimedia development and game software development.

PyOpenGL-the module encapsulates the "OpenGL application programming interface", through which python programmers can integrate 2D and 3D graphics in the program.

NumPy, NumArray, and SAGE ---- NumArray is an extension library of Python. it is mainly used to process fixed arrays of any dimension. In short, it is a matrix library. Its low-level code is written in C, so the speed advantage is obvious. NumPy is the successor of Numarray, used to replace NumArray.

SAGE is a mathematical software package based on NumPy and several other tools. it aims to replace Magma, Maple, Mathematica and Matlab.

MySQLdb module ---- used to connect to the MySQL database. The ZMySQLDA module for zope can be used to connect to the mysql database in zope.

PyGTK-GTK + library used for GUI program development. GTK is the library used to implement GIMP and Gnome. With it, you can confidently try making your own Photoshop.

PyQt ---- used for the Qt Development Library. QT is the database that implements the KDE environment. it consists of a series of modules, including qt, qtcanvas, qtgl, qtnetwork, qtsql, qttable, qtui and qtxml, contains 300 classes and more than 5750 functions and methods. PyQt also supports a module called qtext, which contains a QScintilla Library. This library is the Qt interface of the Scintillar editor class.

PyMedia-python module for multimedia operations. It provides rich and simple interfaces for multimedia processing (wav, mp3, ogg, avi, px, dvd, cdda etc ). It can be used on Windows and Linux platforms.

Psyco-a code accelerator that increases code execution speed to the same level as the compilation language.

Python-ldap-provides a set of object-oriented APIs to conveniently access the ldap directory service in python, which is based on OpenLDAP2.x.

Smtplib module-send an email.

Ftplib module ---- defines FTP classes and some methods for ftp programming on the client. We can use python to compile an ftp client program for downloading files or image sites. For more information about the ftp protocol, see RFC959.

The xmpppy module-the Jabber server adopts the developed XMPP protocol, and Google Talk is also an IM system using the XMPP protocol. There is an xmpppy module that supports this protocol. That is to say, we can use this module to communicate with the Jabber server. is it Cool.
