Please read our best practices on posting topics and edit your post accordingly. In particular, you need to enclose your input file in backticks for this question. For debugging syntax errors, we need to know exactly what input file you attempted to run.
Thank you for the suggestions. That is in fact one question I had as well, which is what is input file. I don’t think I have specified any input file here. All the things for the code has been posted, and the error messages are pretty short, which said there are syntax errors in those two positions. Please let me know if this is clear.
I’ve edited your question to be more consistent with the guidelines I posted earlier.
Psi4 has been trying to serve computational chemists long before OpenFermion and related projects. For computational chemists, the typical workflow is running an executable. The executable will read and parse a structured file (the input file) instructing the executable on what computations to perform. The first piece of “code” you posted is one of these structured files. This is not a valid Python code, and it is expected to give a SyntaxError if you try to run it as one, because it is not intended to be valid Python syntax. If you want to run “code” written like that, you need to run Psi4 as an executable rather than as a Python script.
The second “code” is a Python script and can be executed as any other Python script.
