CategoricalIndex.is_categorical()

DatetimeIndex.is_object()

pandas.date_range(start=None, end=None, periods=None, freq='D', tz=None, normalize=False, name=None, closed=None, **kwargs)

Series and Index are equipped with a set of string processing methods that make it easy to operate on each element of the array. Perhaps most importantly, these methods

DataFrame.last_valid_index()

DataFrameGroupBy.cov(min_periods=None) Compute pairwise covariance of columns, excluding NA/null values

TimedeltaIndex.get_values()

CategoricalIndex.append(other)

Panel.get_value(*args, **kwargs)

Series.tz_convert(tz, axis=0, level=None, copy=True)
