我是Python的新手,我正在尝试理解一个问题,我在创建包时会看到这个问题.我有以下文件结构:(工作目录是/ my/Python/jmLib2)

/my/Python/jmLib2

---------------------------------
cat ./jmLib2/Pots.py
#!/usr/bin/python

def Pots():

---------------------------------
cat ./jmLib2/__init__.py
from Pots import Pots

---------------------------------
cat ./Test2.py
#!/usr/bin/python
from Phone import Pots

import os.path
print ("OS:"+str(os.path))

Pots()

当我现在这样做:

python2 Test2.py
OS:<module 'posixpath' from '/usr/lib/python2.7/posixpath.pyc'>
    I'm Pots Phone*

太棒了......但是,如果我这样做:

python3 Test2.py
Traceback (most recent call last):
  File "Test2.py", line 2, in <module>
    from Phone import Pots
  File "/home/juergen/my/Python/jmLib2/Phone/__init__.py", line 1, in <module>
    from Pots import …
