This code uses a list comprehension to iterate through the original list and only keep the elements that are not empty strings.

It's generally not recommended to ignore exceptions, as they often indicate a problem in the code that should be addressed.

You can use the exclude() method to filter out records where a certain field is not equal to a certain value.

You can expand the output display of a Pandas DataFrame by setting the option 'display.max_columns' in pandas.

This error occurs when the mysql-config command is not in the system's PATH.

It is generally not recommended to remove items from a list while iterating over it because it can cause unexpected behavior.
