pyc文件是二进制文件,可以由python虚拟机直接运行。 Python在执行import语句时,将会到已设定的path中寻找对应的模块。并且把对应的模块编译成相应的PyCodeObject中间结果,然后创建pyc文件,并将中间结果写入该文件。然后,Python会import这个pyc文件,实际上也就是将pyc文件中的PyCodeObject重新复制到内存中。而被直接运行的pyth...
例如,这些包也可以安装在 Python 站点包文件夹中,或者PYTHONPATH环境变量可以被定制为动态地告诉 Python 要搜索哪些文件夹以及它要导入的模块。 那么,在这些选择中,我们选择哪种语法呢?这取决于你的个人喜好和手头的应用。如果products模块中有数十个类和函数我想要使用,我通常使用from ecommerce import products语法导...

This chapter of the manual teaches you how to define your own node packs:defining your first node. Node scripts are meant to be completely independent from one another, that is, they shouldn't import resources from one another. However, when necesary, you can make common resources available ...

import a.b Python 首先引入模块 a,然后引入子模块 a.b。将子模块添加到模块字典中并赋值给变量 a 后,我们就可以将子模块作为模块属性访问了。 可以包含子模块的模块称为包。技术上看,包就是带有 __path__ 属性的模块,通过这个属性,Python 可以找到子模块。引入顶层模块时,Python 会搜索文件夹与 sys.path ...
