Something like this should do it. It gives up immediately on fatal errors
and tries again on temporary ones. (You have to specify what you consider
fatal or temporary, of course.) It uses exponential backup to wait longer
and longer each time you fail, before eventually giving up.
delay = 2
for attempts in range(max_attempts):
try:
command()
except PermanentFailureError:
raise
except TemporaryFailureError:
sleep(delay)
delay *= 2
else:
break
else:
raise RuntimeError("too many attempts")
