Ok, first you need to know what buses exist in the system already. Then work out a bus that fits into one of the gaps.

# now find the first available gap between 1 and 10,000:

available_bus = None
for bus in range(1, 10000):
if bus not in taken_buses:
available_bus = bus
break
print "You can use bus=%d if you want." % available_bus
