1. Update the function here also:

   autogen/autogen/code_utils.py

   Line 246 in c8aca8d

   def _cmd(lang: str) -> str:

   to handle cases when lang is py and Python, converting them to python.
2. Update unit tests to handle py, Python, and python: https://github.com/microsoft/autogen/blob/main/test/coding/test_commandline_code_executor.py#L66

@ekzhu Thankyou for the pointers. Second commit is to revert an accidental import.

It looks good now. In addition to your suggestion I had to add the condition here, in order to pass tests: 99a2a11#diff-7e1e6bfc49ab6dff4b52ba5677edcda6aff4ae436001c46cecd45847d4d71caeR119-R120

Thanks~

This PR is also related to the issue #2096 I made updates to the Gemini branch but not the main branch. This update will be good for many other models.

Thanks. This can be improved by using parametetrized pytest decorators. You can create a separate PR for this.

@pytest.mark.parametrize("input_number, expected_result", [
