Why do python module names have some uppercase letters but are always imported in lowercase?

Whenever I see references to modules like SciPy and NumPy the first letter of each part is capitalized. However they must be imported with all lowercase letters. Why is there this difference?

The difference is basically in branding. As per the style guide: https://www.python.org/dev/peps/pep-0008/#package-and-module-names module names should be short and all lower cased. One reason for that is that when you are importing a module, it would be inconvenient if you had to remember all the capitalizations in the name. Big packages like NumPy and SciPy follow this convention, but when they are referring to themselves (or when others are referring to them) they like to include the stylistic capitalizations. It&#8217;s mostly a style/branding choice.
