| I have a module that contains an import statement that imports a large number of items. This import was failing with the following error message: ImportError: DLL load failed: The specified module could not be found. The message would be so much more helpful if it named the offending DLL and module. |

| I agree. Unfortunately, the operating system does not provide this information. The best I can offer is to run Process Monitor [1] and watch its logs. It should show the paths it attempts to access. [1]: http://technet.microsoft.com/en-us/sysinternals/bb896645 |

| Hello Steve, I'm buying only 50 percent of this. The Python interpreter must know what module it was trying to import, and can at least be able to report that.

| You mean like this: >>> import _ssl Traceback (most recent call last): File "", line 1, in ImportError: DLL load failed: The specified module could not be found. Should include "_ssl" somewhere in the message? That's easy enough, but it's never been what anyone else has meant when they've asked for this, so I assumed you wanted the more helpful message (where it tells you exactly which DLL is missing - libcrypto-1_1-x64.dll in this case - and *that's* the one we can't do). |

| 'Should include "_ssl" somewhere in the message?' Exactly so. If a given import statement imports 30 items, it would be helpful to know which one caused the hickup. Thanks!

| Okay, in that case we're just adding `shortname` into the formatted `message` in _PyImport_FindSharedFuncptrWindows in Python/dynload_win.c I've marked this as "easy (C)" as it seems like a good first contribution for someone. |

| Phillip, when responding by email, please removed the quoted email (except possible for a line or 2) as it becomes noise when your email is placed on the web page. You can see the effect on https://bugs.python.org/issue36266 |
