import interface does not work for me: need to use import Interface #6

Closed VictorNorman closed 6 years ago

VictorNorman commented 6 years ago

I got everything to work by doing

from Interface import Interface

and

from Interface import implements

Using the lowercase interface, I get ImportError: No module named 'interface'.

I'm wondering if this surprises you... Or am I using some other installation of software.

My setup is:

Mac52078:~/classes/design_patterns/python_ifaces vtn2$ python3 Python 3.5.2 (default, Jun 29 2016, 13:43:58) [GCC 4.2.1 Compatible Apple LLVM 7.3.0 (clang-703.0.31)] on darwin Type "help", "copyright", "credits" or "license" for more information.

import Interface

@VictorNorman it looks like you installed the interface python package, which is standalone distribution of zope.interface. This package should be installed via pip install python-interface. The two packages provide similar functionality, but are otherwise unrelated.
