Hi, I am the SymPy bot (v161). I'm here to help you write a release notes entry. Please read the guide on how to write release notes.

Your release notes are in good order.

Here is what the release notes will look like:

• printing
  • Amended a test case of TheanoPrinter constant and complex functions (#20500 by @craymichael)

This will be added to https://github.com/sympy/sympy/wiki/Release-Notes-for-1.9.

<!-- Your title above should be a short description of what
was changed. Do not include the issue number in the title. -->

#### References to other Issues or PRs
Amends https://github.com/sympy/sympy/pull/15885


#### Brief description of what is fixed or changed
`test_complexfunctions` uses `theano_code` instead of `theano_code_` and `test_constantfunctions` uses `theano_function` instead of `theano_function_`, which may yield unexpected results due to how the wrapper handles cache. This PR uses the correct definitions.

This looks good.

I'm going to close and reopen to restart the tests.

I just took care of the merge conflict. This should still be good to merge once the tests finish

Sorry I forgot abut this. Are you aware that in the mean time sympy has now moved to supporting aesara? I'm not sure if that affects this patch or not.

No worries - and I have not, thanks for pointing that out. The move makes sense.

I am not familiar with aesara beyond what Theano was, but the fixes in this PR simply ensure that the theano printer uses the correct wrappers in test functions (just making sure that the cache for theano_code and theano_function is empty by default).

Okay, thanks. I'm reassured to hear from someone who is (I assume) using sympy with theano.
