Series.isnull() [source] Return a boolean same-sized object indicating if the values are null. See also notnull boolean inverse of isnull

Series.isin(values) [source] Return a boolean Series showing whether each element in the Series is exactly contained in the passed sequence of values. Parameters: values : set or list-like The sequence of values to test. Passing in a single string will raise a TypeError. Instead, turn a single string into a list of one element. New in version 0.18.1. Support for values as a set Returns: isin : Series (bool dtype) Raises: TypeError If values is a string See also pandas.DataFrame.

Series.irow(i, axis=0) [source] DEPRECATED. Use .iloc[i] or .iat[i] instead

Series.interpolate(method='linear', axis=0, limit=None, inplace=False, limit_direction='forward', downcast=None, **kwargs) [source] Interpolate values according to different methods. Please note that only method='linear' is supported for DataFrames/Series with a MultiIndex. Parameters: method : {?linear?, ?time?, ?index?, ?values?, ?nearest?, ?zero?, ?slinear?, ?quadratic?, ?cubic?, ?barycentric?, ?krogh?, ?polynomial?, ?spline?, ?piecewise_polynomial?, ?from_derivatives?, ?pchip?, ?akim

Series.imag

Series.iloc Purely integer-location based indexing for selection by position. .iloc[] is primarily integer position based (from 0 to length-1 of the axis), but may also be used with a boolean array. Allowed inputs are: An integer, e.g. 5. A list or array of integers, e.g. [4, 3, 0]. A slice object with ints, e.g. 1:7. A boolean array. A callable function with one argument (the calling Series, DataFrame or Panel) and that returns valid output for indexing (one of the above) .iloc will raise

Series.iget_value(i, axis=0) [source] DEPRECATED. Use .iloc[i] or .iat[i] instead

Series.iget(i, axis=0) [source] DEPRECATED. Use .iloc[i] or .iat[i] instead

Series.idxmin(axis=None, skipna=True, *args, **kwargs) [source] Index of first occurrence of minimum of values. Parameters: skipna : boolean, default True Exclude NA/null values Returns: idxmin : Index of minimum of values See also DataFrame.idxmin, numpy.ndarray.argmin Notes This method is the Series version of ndarray.argmin.

Series.idxmax(axis=None, skipna=True, *args, **kwargs) [source] Index of first occurrence of maximum of values. Parameters: skipna : boolean, default True Exclude NA/null values Returns: idxmax : Index of maximum of values See also DataFrame.idxmax, numpy.ndarray.argmax Notes This method is the Series version of ndarray.argmax.
