pyarrow.compute.is_in#
- pyarrow.compute.is_in(values, /, value_set, *, skip_nulls=False, options=None, memory_pool=None)#
Find each element in a set of values.
For each element in values, return true if it is found in a given set of values, false otherwise. The set of values to look for must be given in SetLookupOptions. By default, nulls are matched against the value set, this can be changed in SetLookupOptions.
- Parameters:
- valuesArray-like or scalar-like
Argument to compute function.
- value_set
Array Set of values to look for in the input.
- skip_nullsbool, default
False If False, nulls in the input are matched in the value_set just like regular values. If True, nulls in the input always fail matching.
- options
pyarrow.compute.SetLookupOptions, optional Alternative way of passing options.
- memory_pool
pyarrow.MemoryPool, optional If not passed, will allocate memory from the default memory pool.
