from模块名import函数/类/变量 1. 代码示例 假设有一个名为maths的模块,其中定义了一些数学相关的函数和常量。我们可以使用from关键字将模块中的特定内容导入到当前模块中,以便直接使用。 下面的示例演示了如何使用from关键字导入maths模块中的add函数和PI常量: AI检测代码解析 frommathsimportadd,PI result=add(2,3...
同样是派这么一个变量,但是呢,它是来自于不同的名字空间买,呃,MYPA里头有这么一个东西,呃,呃,My file里面有这么一个东西,Maths里面也有这么一个东西,不同的名族空间都可以有派相同的变量名,互不干扰。哎,所以这个Python之禅说什么呢?说这个name spaces啊,One honking great idea, 名字空间是一个伟大的主意...
First of all, let's talk about your OS. Python is fully integrated and most likely already installed in basically almost every Linux distribution. If you have a Mac, it's likely that Python is already there as well (however, possibly only Python 2.7), whereas if you're using Windows, y...
