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))
