What does following code means in python (snippet of locust code)?

Question

I want to understand what self means in the lambda function.

In the Locust tool I found this code :

import random

class WebsiteUser(HttpLocust):
    task_set = UserBehaviour
    wait_function = lambda self: random.expovariate(1)*1000

Can anyone explain what self means in the lambda function? Or in short what is happening in this lambda function?

`self` as the first parameter of a method means the instance being used to call the method. Lambda functions work the same as `def` statements. — khelwood, Jul 18 '19 at 11:46

Your definition is equivalent to

class WebsiteUser(HttpLocust):
    task_set = UserBehaviour
    def wait_function(self):
        return random.expovariate(1)*1000

self is the conventional name for the first argument to an instance method, whether you use a def statement or a lambda expression to define the method.
