There is an additional wrinkle: the module's name depends on whether it was imported "directly" from the directory it is in or imported via a package. This only makes a difference if you run Python in a director
通过这种方式,即使模块用户通过import *调用您的包,也只有pub_fun1和pub_fun2会被通配符导入。Pub_fun3将对调用者保密。 如果你的同事固执地坚持使用import *,你可以把下面他们import *的True和False颠倒过来,来说服他们: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 False,True=True,False # works only...
虽然可能会出现某些副作用,例如导入父包,以及更新各种缓存(包括 sys.modules),但只有 import 语句执行名称绑定操作。 二、查找 Module 的方式 When a module named spam is imported, the interpreter first searches for a built-in module with that name. If not found, it then searches for a file named ...

这篇博客的雏形,严格来讲,在我脑海中浮现已有近一年之久,起源于我之前在写一个python模块并用jupyter notebook测试时发现,当在一个session中通过import导入模块,修改模块再次通过import导入该模块时,模块修改并不会生效。至此,通过一番研究发现,python 导入机制(import machinery)对于我们理解python这门语言,有着至关重...

If a module has already been imported, Python is smart enough not to try to re-import it. However, depending on the point at which each module is attempting to access functions or variables defined in the other, you may indeed run into problems. So returning to our example, when we ...
