There can be zero or more elif parts, and the else part is optional. The keyword ‘elif’ is short for ‘else if’, and is useful to avoid excessive indentation. An if … elif … elif … sequence is a substitute for the switch or case statements found in other languages. 4.2 for St...
Python has seen three primary evolutions: Python 1.0, released in 1994; Python 2.0, in 2000; and Python 3.0, in 2008. Notably, Python 3.0 is not backward-compatible with earlier versions. By the early 2020s Python had become one of the most extensively used programming languages worldwide....

Note: Singleton classes aren’t really used as often in Python as in other languages. The effect of a singleton is usually better implemented as a global variable inside a module. Class decorators are less common than function decorators. You should document these well, so that your users know...
Unlike in other languages, Python statements are not normally terminated with a delimiter, such as a semicolon (;). When a statement is too long to fit on a single physical line, you can join two adjacent physical lines into a logical line by ensuring that the first physical line has no...
Other languages built in RPython Monte - secure distributed computation Monte is a "nascent dynamic programming language reminiscent of Python andE. It is based upon The Principle of Least Authority (POLA), which governs interactions between objects, and a capability-based object model, which grants...

In Python, we allow concatenation in comparison operators. For example, to test if a value is between -1 and +1, we can do: 1 2 if value > -1 and value < 1: ... but we can also do: 1 2 if -1 < value < 1: ... Built-in Data Structures As in many other languages,...
Other programming languages often use curly-brackets for this purpose.(Python 依赖缩进,使用空格来定义范围;例如循环、函数和类的范围。其他编程语言通常使用花括号来实现此目的。) Python Indentation (Python 缩进) Indentation refers to the spaces at the beginning of a code line. 缩进指的是代码行开头的...
