How can I tell PyCharm what type a parameter is expected to be?

by

Yes, you can use special documentation format for methods and their parameters so that PyCharm can know the type. Recent PyCharm version supports most common doc formats.

For example, PyCharm extracts types from @param style comments.

See also reStructuredText and docstring conventions (PEP 257).

Another option is Python 3 annotations.

Please refer to the PyCharm documentation section for more details and samples.
