exception pandas.errors.InvalidIndexError[source]#

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.
