'DataFrame' object has no attribute 'jion'

The error message suggests that you are trying to use the `jion` method on a `DataFrame` object in your code, but this method does not exist for `DataFrame`.

It is possible that you meant to use the `join` method instead, which is a valid method for `DataFrame`. The `join` method is used to merge two or more `DataFrame` objects based on a common column or index.

If this is not the case, please provide more information about your code and the specific line where the error occurs so that I can assist you better.
