Or perhaps you don't actually want to run moduleX, you just want to run some other script, say myfile.py, that uses functions inside moduleX. If that is the case, put myfile.py somewhere else – not inside the package directory – and run it. If inside myfile.py you do things ...
Since the argument is amodulename, you must not give a file extension (.py). The module name should be a valid absolute Python module name, but the implementation may not always enforce this (e.g. it may allow you to use a name that includes a hyphen). Package names (including names...
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...
Regular package,即常规包,一般是指每一个文件夹或子文件夹下都包含__init__.py(模块初始化文件,可以为空)。默认情况下,submodules 和 subpackages不会被导入,而通过__init__.py可以将任意或全部子模块按照你的想法进行导入。比如在我写的一个示例packagepython_dotplot中,可以通过__init__.py的__all__默认...
python进阶(28)import导入机制原理,前言在Python中,一个.py文件代表一个Module。在Module中可以是任何的符合Python文件格式的Python脚本。了解Module导入机制大有用处。1.Module组成一个.py文件就是一个module。Module中包括attribute,function等。这里说的a
执行main.py,可以证实动态加载了archives包,__import__返回的模块也是archives模块 C:\Users\Admin\Documents\Python3\importtest>python main.py main archives.__index__ hello archives Traceback (most recent call last): File "main.py", line 5, in <module> archives.user AttributeError: module 'archi...
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: ...
Functions such as importlib.import_module() and built-in import() can also be used to invoke the import machinery. The import statement combines two operations; it searches for the named module, then it binds the results of that search to a name in the local scope. The search operation ...

It's very simple to create a Python module. You just need to write Python code in a file and save that file with a .py extension. Example to Create Python Modules Here is an example where we create two modules:mycheck.pyandmymath.py. These modules contain functions for number checking...
