Python relative import local package module file All In One

absolute imports vs relative imports

absolute Imports / 绝对导入

project package

$ tree
└── project
    ├── package1
    │   ├── module1.py
    │   └── module2.py
    └── package2
        ├── __init__.py
        ├── module3.py
        ├── module4.py
        └── subpackage1
            └── module5.py

Recall the file contents:

package1/module2.py contains a function, function1.
package2/__init__.py contains a class, class1.
package2/subpackage1/module5.py contains a function, function2.

You can import class1 and function2 into the package2/module3.py file this way:

# package2/module3.py

from . import class1
from .subpackage1.module5 import function2
