[New-bugs-announce] [issue17108] import silently prefers package over module when both available

[Shai Berger]

New submission from Shai Berger:

Consider the following directory structure:

a-\
  __init__.py
  b.py
  b-|
    __init__.py

Now, in Python (I checked 2.7.3 and 3.2.3, haven't seen the issue mentioned anywhere so I suspect it is also in later Pythons), if you import a.b, you always get the package (that is, the b folder), and the module (b.py) is silently ignored. I tested by putting the line """print("I'm a package")""" in a/b/__init__.py and """print("I'm a module")""" in a/b.py.

This becomes a real problem with tools which find modules dynamically, like test harnesses.

I'd expect that in such cases, Python should "avoid the temptation to guess", and raise an ImportError.

Thanks, Shai.
