python关键字和保留字

关键词 (Keywords)

Keywords are the reserved words in Python programming language (and, any other programming languages like C, C++, Java, etc) whose meanings are defined and we cannot change their meanings. In python programming languages, keywords are the case sensitive.

关键字是Python编程语言(以及其他任何编程语言，如C，C ++，Java等)中的保留字，其含义已定义，我们无法更改其含义。在python编程语言中，关键字区分大小写。

Note: We cannot use any reserved words (which are known as Keywords) as an identifier (like a variable name, function name, etc).

注意：我们不能使用任何保留字(称为关键词 )作为标识符(如变量名，函数名等)。
