__init__.py requires two underscores before and after init. You have only one on either side. — Martijn Pieters

Python module names are case sensitive as well; your package is called info, all lower case, but your code imports Info, with a capital I. — Martijn Pieters

You have made two mistakes:

To create a package, the file must be named __init__.py (double underscores on either side), not _init_.py.
Python is case sensitive. You named your package info (lowercase), but try to import Info (uppercase I); these don't match. Rename one or the other to match case correctly.
