"executable not specified" error in PyCharm

Question

When I try to run a python script in PyCharm, I get this error message:

error running myscript: Executable is not specified

and the script does not run. How do I run my script through PyCharm?

File -> Settings -> Project -> Project Interpreter, and then select an interpreter at the right.

It looks like this on PyCharm Community Edition 4.0.3:

The official JetBrains guide to setting up an interpreter can be found here.
