I wrote the below code

    if (not FacilityUser.objects.filter(username=coach_name)):
        class ContextWithMixin(FacilityMixins, ):
            def __init__(self):
                self.browser = context.browser
        context_wm = ContextWithMixin()
        context_wm.create_teacher(username=coach_name, password=coach_pass)
    facility = FacilityUser.objects.get(username=coach_name).facility.id
    _login_user(context, coach_name, coach_pass, facility=facility)
