the location where the import statement is. There are two types of relative imports: implicit and explicit. Implicit relative imports have been deprecated in Python 3, so I won’t be covering them here.

If you’ve worked on a Python project that has more than one file, chances are you’ve had to use an import statement before. In this tutorial, you’ll not only cover the pros and cons of absolute and relative imports but also learn about the best practi
参考Python 的 PEP 328提案,相对导入基于模块的__name__变量进行搜索。 Relative imports use a module'snameattribute to determine that module's position in the package hierarchy. If the module's name does not contain any package information (e.g. it is set to 'main') then relative imports are...
首先,运行主程序python main.py,一切正常。再以脚本的形式运行模块python spider/realtime/overview.py,报错:ImportError: attempted relative import with no known parent package。 经过一番搜索,查阅了一些文章,终于搞明白,原来在 Python 中,相对导入的实现,是极度依赖__name__内置变量的。当模块以import导入的方式...
from __future__ import absolute_import 这样做的好处是可以避免模块名冲突的问题,同时也可以提高代码的可读性和可维护性。使用嵌套的absolute_imports后,可以明确指定要导入的模块的绝对路径,而不会受到当前模块所在目录的影响。 在实际应用中,嵌套的absolute_imports可以用于解决模块名冲突的问题,尤其是在大型项目中,...
For more information, see Absolute vs Relative Imports in Python. Python’s Import Path How does Python find the modules and packages it imports? You’ll see more details about the mechanics of the Python import system later. For now, just know that Python looks for modules and packages in...
1 Imports快速介绍 Python模块是具有.py扩展名的文件,而Python包是其中具有模块的任何文件夹(或者在Python 2中是包含__init__.py文件的文件夹)。当一个模块中的代码需要访问另一模块或程序包中的代码时,你需要导入它。 但是如何一个模块,假设您像这样导入os模块: ...
Absolute vs. explicit relative import of Python module 我想知道在Python应用程序中导入包的首选方法。我有这样的包装结构: 1 2 3 project.app1.models project.app1.views project.app2.models project.app1.views进口project.app1.models和project.app2.models。有两种方法可以做到这一点。
3. Use absolute imports: If you don't want to convert your project into a package, you can use absolute imports instead of relative imports. Absolute imports involve specifying the full path to the module or package you want to import. For example, instead of from .mymodule import func, ...
