Why I can't import module from the same directory in python

Question

Project structure
test/
--test.py
--pkg/
----p1.py
----p2.py

test.py

import pkg.p1  
pkg.p1.print_p1()

p1.py

import p2  
def print_p1():  
  print('in p1')  
  p2.print_p2()

p2.py

def print_p2():  
    print('in p2')

When I run test.py, I gets ModuleNotFoundError: No module named 'p2'.
Tried adding empty __init__.py but still no luck. Any expert can help?
Thanks in advance.

You are not using p2 in your test.py file. so the error is related to using p2 in yout p1.py file — nCoder, Nov 30 '21 at 17:01

@nCoder Traceback (most recent call last): File "h:\python\playground-main\test\pkg\p1.py", line 3, in from pkg.p2 import print_p2 ModuleNotFoundError: No module named 'pkg' I got this error — William Fung, Dec 01 '21 at 07:38
fyi, in sys.path it contains 'h:\\python\\playground-main\\test', I don't understand why when test.py call p1.py, it throws an error but it doesn't happen when I run p1.py itself — William Fung, Dec 01 '21 at 07:56
This was assuming you have the __ init __.py in your pkg directory as you mentioned in the question. — nCoder, Dec 01 '21 at 14:15

Change your p1.py file to this and add a init.py in your pkg directory:

from pkg.p2 import print_p2
def print_p1():
  print('in p1')
  print_p2()

I found that adding from .p2 import print_p2 into p1.py would make test.py work, though p1.py itself would have error

ImportError: attempted relative import with no known parent package.

Thanks all for your help
