Conditions

Speed up your workflow!

PyStreamAPI presents four distinct groups of conditions for your convenience. Within these groups, you'll find a variety of conditions with varying parameters. For instance, certain conditions like even() do not require any parameters, while others such as less_than(n) involve specifying a single parameter.

Moreover, PyStreamAPI provides a single combiner that empowers you to seamlessly merge multiple conditions, thereby enhancing your ability to manipulate data more effectively.

Import

All conditions can be imported from:

from pystreamapi.conditions import …

In order to import all conditions from a specific group, use these imports:

from pystreamapi.conditions.numeric import *
from pystreamapi.conditions.types import *
from pystreamapi.conditions.string import *
from pystreamapi.conditions.date import *

Combiner

one_of(*conditions) checks if one of the given conditions are fulfilled. You can pass as many conditions as you want.

from pystreamapi import Stream
from pystreamapi.conditions import prime, even, one_of

Stream.of([1, 2, 3, 4, 5]) \
    .filter(one_of(even(), prime())) \
    .for_each(print)
