Importing a module no longer works

[andy31lewis]

Importing a module worked correctly in 3.7.1 but in 3.7.2 the import fails with "ImportError: No module named xxxxxxx".
This is the case no matter whether the module is a file module.py, or a folder containing an __init__.py file, or an import from within a folder import folder.module as mymodule.

Having done some digging, I find that the change seems to have been introduced in commit 4894051 Fixes #1093 : wrong assignment in "for x in empty range", on April 17th, although I can't see what that title has to do with importing a module :-)

Thank you as always
Andy

Many thanks for reporting this very soon after the release of version 3.7.2... It's the kind of bug that doesn't show in the development environment, but crashes everything in an environment created by python -m brython --install. I have published release 3.7.3 with a bug fix.

By the way, the bug was indeed introduced by the previous commit, 6c8b2fa, with a name more related to the issue : Limit the number of tries when importing from a module in the standard library

I try to import regex module from a Brython script in my Client folder. regex is located at ...\Client\resources\backend\javascript_packages\Brython\Lib\site-packages\regex. I do:

import regex and I get this error:

I'm using CEF.
the init.py contains from .regex import *. In the regex folder there is is a regex.py script.
The init.py is present in the regex folder. If you look at the part regex was not found at url file:///C:/Users/hp/Documents/Programming/Web%20development/File%20content%…es/backend/javascript_packages/Brython/Lib/site-packages/regex/__init__.py it looks like resources folder isn't present, but there's ...es which I think is an abbreviation for that folder. So the error shows the right paths to check, but the module isn't found. I'm 100% sure that the modules are in the correct folders with the correct names.
