Python
if __name__ == '__main__'
判断是否是在直接运行该.py文件
__name__ 算是个全局变量, 如果为直接运行 python SELF.py 则判断为1

identifier 标识符ID | Unique

Identifier refers to name given to entities such as variables, functions, structures etc.

type qualifier 类型限制

In the C, C++, and D programming languages, a type qualifier is a keyword that is applied to a type, resulting in a qualified type.
For example, const int is a qualified type representing a constant integer, while int is the corresponding unqualified type, simply an integer.
In D these are known as type constructors, by analogy with constructors in object-oriented programming.
