There could be multiple reasons for obtaining different outcomes in LeetCode as opposed to the Python console:

1. Input Data: The input data in LeetCode may be different from what you used in the Python console. Make sure you are using the same input data in both cases.

2. Output Format: The output format may be different in LeetCode as compared to the Python console. For example, you may need to return a list or a string in a specific format in LeetCode. Make sure you are returning the output in the correct format.

3. Compiler Environment: LeetCode uses its own compiler environment to evaluate the code, which may be different from the Python environment on your local machine. This may result in differences in behavior.

4. Code Execution: If your code has any input/output statements or uses external modules that are not available in LeetCode's environment, you may get different outcomes.

5. Bugs: It is also possible that your code has bugs that you did not encounter in the Python console. It is important to debug your code thoroughly before submission.
