Using random in a simple example

I've been trying to modify the simple example provided and make it randomly trade as long as it stays within it's notional limits. When running I get the following error:

Something went wrong on our end and we've been notified about it. Sorry for the inconvenience.
OSError:
File test_algorithm_sycheck.py:6, in initialize
File random.py:111, in seed

Am I doing something wrong, is this an actual problem with Quantopian?

import random

def initialize(context):  
  context.aapl = sid(24)  
  random.seed(None)  
  context.max_notional = 1000000.1  
  context.min_notional = -1000000.0

def handle_data(context, data):  
  price = data[context.aapl].price  
  notional = context.portfolio.positions[context.aapl].amount * price  
  if random.randrange(0,1) == 0 and notional > context.min_notional:  
    order(context.aapl,-100)  
  elif notional < context.max_notional:  
    order(context.aapl,+100)

That looks like a problem on our end. I'll look into it. Thanks for telling us about it.

Cheers Dan. For future reference, is there a better channel to use to get in touch with you guys about stuff like this or is posting here ok?

Random works fine now. Thanks again for bringing it up.
