Python is a high-level, general-purpose programming language known for its readability and simplicity. Learn the features, applications, and advantages of Python.
Python是一种面向对象、直译式的电脑程序语言。它包含了一组功能完备的标准库,能够轻松完成很多常见的任务。它的语法简单,与其它大多数程序设计语言使用大括号不一样,它使用缩进来定义语句块。与Scheme、Ruby、Perl、Tcl等动态语言一样,Python具备垃圾回收功能,能够自动管理内存使用。它经常被当作脚本语言用于处理系统管理...
machine learning (ML) andweb development, Python yields code that is easy to read, understand and learn. Python's indentation requirements for source statements help make the code consistent andeasy to read.Applicationsdeveloped with Python codetend to be smallerthan software built ...
Socket programming is a technique for connecting two applications, or nodes, on a network by using sockets as endpoints for transferring and receiving data. It is a key networking concept that allows programs to communicate data over local and remote networks. In Python, the socket module contains...
pandas is an open-source software library built on Python for data analysis and data manipulation. The pandas library provides data structures designed specifically to handle tabular datasets with a simplified Python API. pandas is an extension of Python to process and manipulate tabular data, impleme...

Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
Python is dynamically typed unlike C++ and Java, as a result, variable types are inferred atruntime. This simplifies development but potentially at the cost of performance. Python uses an automatic garbage collector like Java and doesn't use the C++ const keyword. ...

PEP 0238: An expression like 1/2 returns a float. Use 1//2 to get the truncating behavior. (The latter syntax has existed for years, at least since Python 2.2.) The sys.maxint constant was removed, since there is no longer a limit to the value of integers. However, sys.maxsize ca...
