# 2.5.13.47. SetProperty

class buildbot.steps.master.SetProperty

`SetProperty` takes two arguments of `property` and `value` where the `value` is to be assigned to the `property` key. It is usually called with the `value` argument being specified as an Interpolate object which allows the value to be built from other property values:

    from buildbot.plugins import steps, util

    f.addStep(
        steps.SetProperty(
            property="SomeProperty",
            value=util.Interpolate("sch=%(prop:scheduler)s, worker=%(prop:workername)s")
        )
    )
