How can I retrieve the values from a dataset using ast if I am receiving an empty list?

edit

If you are receiving an empty list when using ast to retrieve values from a dataset, there could be several reasons why this is happening. Here are a few things you can check:

1. Make sure that the dataset you are trying to retrieve values from actually contains data. You can do this by printing out the dataset or using the len() function to check the length of the dataset.

2. Check that you are using the correct syntax for retrieving values with ast. If you are not sure, you can refer to the documentation or examples online to ensure that you are using ast correctly.

3. Verify that the values you are trying to retrieve actually exist in the dataset. It's possible that the values you are looking for are not present in the dataset, which would cause ast to return an empty list.

4. If you are using ast to parse JSON data, make sure that the data is valid JSON. If the data is not properly formatted, ast may not be able to retrieve the values you are looking for.

5. Check for any errors or exceptions that may be occurring during the retrieval process. You can use try/except blocks to catch any errors that may be occurring and handle them accordingly.
