Resolving these constructs usually involves techniques like Dependency Injection.

It is, however, rather simple to fix this error:

In calendarLib.py:

import homePageLib

    def clickHomePageLink(self):
        [...]
        return homePageLib.HomePage()

The code at module level is executed at import time. Using the from [...] import [...] syntax requires the module to be completely initialized to succeed.

A simple import [...] does not, because no symbols are accessed, thus breaking the dependency chain.
