Series.reset_index
Reset the index of a series.
danfo.series.reset_index(kwargs) [source]
Generate a new Series with the index reset. This is useful when the index needs to be treated as a column, or when the index is meaningless and needs to be reset to the default before another operation.
Parameters | Type | Description | Default |
kwargs | Object | kwargs is an object {} with key inplace with a boolean value. e.g {inplace: false} | inplace:false |
Returns : Series
