我们使用sys.modules获取当前已加载的所有模块,并通过inspect获取当前模块的信息。 defget_imported_modules():current_module=inspect.getmodule(inspect.currentframe())# 获取当前模块imported_modules={name:moduleforname,moduleinsys.modules.items(
执行过code object的module对象就算import完了。python会将他cache在sys.modules里。当有别的地方也import...

name: The name of the module to be imported (in string form).globals/locals：通常传入全局和局部命名空间字典，一般使用默认值即可。globals/locals: Usually pass the global and local namespace dictionaries; default values are generally used.fromlist：指定从模块中导入的子模块或对象列表。fromlist: ...
根据“华丽分界线”所表达的成果,我们注意到只有第一次导入时Stat模块被真正运行并打印了"Stat module imported."的信息。模块只在第一次被导入时被运行是一个重要的特性:首先当然节省时间;其次,当A模块引用B模块,B模块引用A模块的复杂状态发生时,该特性可以避免无穷的导入循环。
Standard modules can be imported the same way as we import our user-defined modules. Import Python Standard Library Modules The Python standard library contains well over 200 modules. We can import a module according to our needs. Suppose we want to get the value of pi, first we import the...
from IsDir import * 只能保证IsDir被imported, 所以此时IsDir里的modules是无法被imported, 此时只有如我上面所写的代码所示才能正确执行,否则是错误的。官方解释为:import IsDir.A并无任何意义,只有接着执行from IsDir import *后,import IsDir.A语句里的module A才会被定义,所以完整的调用因改为: 1. import IsDi...
1.1.3: Modules and Methods 模块和方法 让我们谈谈模块。 Let’s talk a little bit about modules.Python模块是代码库,您可以使用import语句导入Python模块。 Python modules are libraries of code and you can import Python modules using the import statements. 让我们从一个简单的案例开始。 Let’s start ...
In summary, __all__ is used by both packages and modules to control what is imported when import * is specified. But the default behavior differs: For a package, when __all__ is not defined, import * does not import anything. For a module, when __all__ is not defined, import *...
It is possible to modify the names of modules and their functions within Python by using theaskeyword. You may want to change a name because you have already used the same name for something else in your program, another module you have imported also uses that name, or you may want to ...
