TypeError: select_all() missing 1 required positional argument: 'table_name'

This error message indicates that a function called "select_all()" requires an argument called "table_name", but it is not being passed when the function is called.

To fix this error, you need to provide the missing argument when calling the function. For example, if the table you want to select from is called "customers", you would call the function like this:

select_all("customers")

Make sure the argument is spelled exactly as it appears in your database.
