cudf.DataFrame.eq#

DataFrame.eq(other, axis='columns', level=None, fill_value=None)[source]#

Get Equal to of DataFrame or Series and other, element-wise (binary operator eq).

Equivalent to frame + other, but with support to substitute a fill_value for missing data in one of the inputs.

Parameters:

otherscalar, sequence, Series, or DataFrame: Any single or multiple element data structure, or list-like object.
axisint or string: Only 0 is supported for series, 1 or columns supported for dataframe
levelint or name: Broadcast across a level, matching Index values on the passed MultiIndex level. Not yet supported.
fill_valuefloat or None, default None: Fill existing missing (NaN) values, and any new element needed for successful DataFrame alignment, with this value before computation. If data in both corresponding DataFrame locations is missing the result will be missing.

Returns:

DataFrame or Series: Result of the arithmetic operation.

Examples

DataFrame

>>> df = cudf.DataFrame(
...     {'angles': [0, 3, 4], 'degrees': [360, 180, 360]},
...     index=['circle', 'triangle', 'rectangle']
... )

>>> df.eq(1)
        angles  degrees
circle      False    False
triangle    False    False
rectangle   False    False

Series

>>> a = cudf.Series([1, 1, 1, None], index=['a', 'b', 'c', 'd'])
>>> b = cudf.Series([1, None, 1, None], index=['a', 'b', 'd', 'e'])

>>> a.eq(b)
a    True
b    <NA>
c    <NA>
d    <NA>
e    <NA>
dtype: bool
>>> a.eq(b, fill_value=0)
a    True
b   False
c   False
d   False
e    <NA>
dtype: bool
