Handle error 152 “Insufficient points”

Python version 2 or 3 using JSON with the Requests library

In version 5 of the Yandex Direct API, points are awarded to all advertisers every 60 minutes, but each advertiser has its own schedule for awarding points that is not related to the beginning of the astronomical hour. The example shows how requests are executed if the first request returns the 152 error code.

For demonstration purposes, it uses the sleep function, which allows you to set delays for running the script. The delays are set in seconds in the delays array, so that after the first attempt no more than 5 repeat requests are sent with increasing intervals that cover the next 60 minutes after receiving the first error.
