许多库已经重写,以便与两个版本兼容,主要利用了six库的功能(名称来源于 2 x 3 的乘法,因为从版本 2 到 3 的移植),它有助于根据使用的版本进行内省和行为调整。根据 PEP 373(legacy.python.org/dev/peps/pep-0373/),Python 2.7 的生命周期结束(EOL)已经设定为 2020 年,不会有 Python 2.8,因此对于在 Pyth...
You can override the default operator precedence using parentheses to group terms as you do in math. The subexpressions in parentheses will run before expressions that aren’t in parentheses. Here are some examples that show how a pair of parentheses can affect the result of an expression: Pyth...

In this section, you’ll look at how to override .__mod__() so that you can use the modulo operator with your own classes. For this example, you’ll be working with a Student class. This class will track the amount of time a student has studied. Here’s the initial Student class...
