Series.mask(cond, other=nan, inplace=False, axis=None, level=None, try_cast=False, raise_on_error=True) [source] Return an object of same shape as self and whose corresponding entries are from self where cond is False and otherwise are from other. Parameters: cond : boolean NDFrame, array or callable If cond is callable, it is computed on the NDFrame and should return boolean NDFrame or array. The callable must not change input NDFrame (though pandas doesn?t check it). New in version 0.1

Series.item() [source] return the first element of the underlying data as a python scalar

DataFrame.combine(other, func, fill_value=None, overwrite=True) [source] Add two DataFrame objects and do not propagate NaN values, so if for a (column, time) one frame is missing a value, it will default to the other frame?s value (which might be NaN as well) Parameters: other : DataFrame func : function fill_value : scalar value overwrite : boolean, default True If True then overwrite values for common keys in the calling frame Returns: result : DataFrame

This is a repository for short and sweet examples and links for useful pandas recipes. We encourage users to add to this documentation. Adding interesting links and/or inline examples to this section is a great First Pull Request. Simplified, condensed, new-user friendly, in-line examples have been inserted where possible to augment the Stack-Overflow and GitHub links. Many of the links contain expanded information, above what the in-line examples offer. Pandas (pd) and Numpy (np) are the only

MultiIndex.min() [source] The minimum value of the object

DataFrame.notnull() [source] Return a boolean same-sized object indicating if the values are not null. See also isnull boolean inverse of notnull

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

DatetimeIndex.is_month_start Logical indicating if first day of month (defined by frequency)

DatetimeIndex.dtype_str = None

Index.values return the underlying data as an ndarray
