wait-for

wait-for

Introduction

Waits for a certain amount of time for an action to complete Designed to wait for a certain length of time, either linearly in 1 second steps, or exponentially, up to a maximum. Returns the output from the function once it completes successfully, along with the time taken to complete the command.

.. note:: If using the expo keyword, the returned elapsed time will be inaccurate as wait_for does not know the exact time that the function returned correctly, only that it returned correctly at last check.

Usage

.. code-block:: python

from wait_for import wait_for

class Incrementor(): value = 0

  def i_sleep_a_lot(self):
      time.sleep(.1)
      self.value += 1
      return self.value

incman = Incrementor() ec, tc = wait_for(incman.i_sleep_a_lot, fail_condition=0, delay=.05) print("Function output {} in time {} ".format(ec, tc))
