Databricks Community Error: SyntaxWarning: "is" with a literal. Did you mean "=="?

Question

Whenever I execute any code on Databricks Community Edition with "is" I get the following error:

SyntaxWarning: "is" with a literal. Did you mean "=="?

For example, the following code will generate the error:

if len(chkRows) is 0:

I have done some research and I believe the issue is with Python 3.8.

How can I overcome this situation without having to re-code all of my work? All of my code is set up in my Python wheel, and I can't find the original code.

I changed the code from "is" to "==", but I get the same error

<command-4177784089769769>:15: SyntaxWarning: "is" with a literal. Did you mean "=="?
  if len(pkRows) == 0:
<command-4177784089769769>:23: SyntaxWarning: "is" with a literal. Did you mean "=="?
  if len(chkRows) == 0:

  if len(pkRows) == 0:
<command-4177784089769769>:23: SyntaxWarning: "is" with a literal. Did you mean "=="?
  if len(chkRows) == 0:

Any thoughts please?
