但若想使用from pacakge_1 import *这种形式的写法,需在 init .py中加上: all = [‘file_a’, ‘file_b’] #package_1下有file_a.py和file_b.py,在导入时 init .py文件将被执行。 但不建议在 init .py中写模块,以保证该文件简单。不过可在 init .py导入我们需要的模块,以便避免一个个导入、方便...

['__doc__','__file__','__loader__','__name__','__package__','__path__','__spec__','congo','zimbabwe'] 可以注意到,当执行完from world_namespace.africa import zimbabwe这句代码后,python就默默的把africa这个名称加到world_namespace这个命名空间了。而zimbabwe将加到world_namespace.afri...

每个模块module 有自己的命名空间,称global namespace,记录模块的变量,包括functions、classes、导入的modules、module级别的变量和常量。 build-in命名空间,它包含build-in function和exceptions,可被任意模块访问。 某段Python代码访问 变量x 时,Python会所有的命名空间中查找该变量,顺序是: ...
from test2 import *print(file_a.a())print(file_b.b())print(file_c.c())print(test_d()) 如果打印有结果,则证明了导入成功,并且导入的是__all__下的模块和函数 3.sys.modules、命名空间 3.1 sys.modules sys.modules是一个将模块名称映射到已加载的模块的字典。可用来强制重新加载modules。Python一...
