什么是兄弟进口？

Question

2to3 - 自动Python 2到3代码翻译 - 修复程序 - 导入注意:

检测兄弟输入并将其转换为相对导入.

Answer 1

从源代码来看：

"""Fixer for import statements.
If spam is being imported from the local directory, this import:
    from spam import eggs
Becomes:
    from .spam import eggs
And this import:
    import spam
Becomes:
    from . import spam
"""

所以兄弟姐妹代表“在同一水平上”。
