[RichardNeumann]

In the documentation of the built-in exceptions hierarchy, there is a "|" missing connecting ImportError and LookupError.

https://docs.python.org/3/library/exceptions.html#exception-hierarchy

From LookupError.__mro__ we can tell, that it is actually derived from Exception, thus there should be a "|" connecting it to the hierarchy under Exception to emphasize that (like between ArithmeticError and AssertionError).

[terryjreedy]

Agreed, like there is a bar between NameError and OSError.

The 2.7 version does not have the problem.

[terryjreedy]

PR-1173 fixed this for 3.7, but it was not backported then. I added a comment there.

[Mariatta]

I will backport the change to 3.6.
