# pandas.errors.InvalidIndexError

exception pandas.errors.InvalidIndexError

  Exception raised when attempting to use an invalid index key.

  This exception is triggered when a user attempts to access or manipulate data in a pandas DataFrame or Series using an index key that is not valid for the given object. This may occur in cases such as using a malformed slice, a mismatched key for a `MultiIndex`, or attempting to access an index element that does not exist.
