Estimate_gaussian_test says "wrong value for mu" when it is a wrong value for var

After successfully defining estimate_gaussian, as an experiment (since earlier I had confusing error messages) I changed the last line to

return mu, var+1

And the error message incorrectly refers to mu instead of var.

AssertionError: Wrong value for mu. Expected: [1, 2, 3] got: [2. 3. 4.]

@toontalk That’s a good catch. If you check the public_tests.py in Lab Files, all the assertion messages for var have mu.

Thank you @toontalk.
