Each operator can be used in a different way for different types of operands. For example,+operator is used foradding two integersto give an integer as a result but when we use it withfloat operands, then the result is a float value and when+is used withstring operands 每个运算符可以以...

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...
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 Python 2 中运行项目的公司来说,现在是需要开始制定升级策略并在太迟之前转移到 Python 3 的时候了。 在我的电脑上(MacBook Pro),这是我拥有的最新 Python 版本:...
