TypeError: 'str' object is not callable

I followed the quick start guide and failed quite in the beginning:

This is my locustfile.py

from locust import HttpLocust, TaskSet

def status(l):
    l.client.get("/status")

class UserBehavior(TaskSet):
    tasks = {"index":2, "profile":1}

    def on_start(self):
        status(self)

class WebsiteUser(HttpLocust):
    task_set = UserBehavior
    min_wait = 5000
    max_wait = 9000

and after starting via

locust --host http://localhost:8080

and selecting any kind of # of user & starting the test, STDOUT gets flooded with

[2016-07-19 09:50:53,764] SGCSNYMACSJUST.local/ERROR/stderr: Traceback (most recent call last):

From documentation:

The tasks attribute is either a list of python callables, or a dict.

You declared it as that's why you have this error.

You can declare the UserBehavior just like that:

class UserBehavior(TaskSet):
    tasks = {status}
