for attempt, elapse in Waiter(
    delays=1,
    timeout=10,
    verbose=True,
):
    # check if should jump out of the polling loop
    if elapse >= 5:
        print("")
        break

print("after waiter")

Parameters:

• delays – delay between each check

• timeout – timeout in seconds

• instant – if True, then the first check is instant

Changed in version 0.2.1: add instant parameter to make the first check instant
