Hi Alex,

I can't get this to run. Could you help?

import random

sequence = ['item1','item2','item1']

previous = None

def weird_appender(sequence):
    first_time_choices = {'item1': 'abc', 'item2': 'def', }
    choices = { None: first_time_choices,
                'item1': {'item1': 'blu', 'item2': 'ghi', },
                'item2': {'item1': 'jkm', 'item2': 'nop', }
              }
    previous = None
    d = choices.get(previous, first_time_choices)
    choose = d.get(item, [''])
    previous = item + random.choice(choose)
    yield previous

print list(weird_appender(sequence))


#    yield item + random.choice(choose)
#    previous = item


#    previous = item + random.choice(choose)
#    yield previous


Thanks,

Malcolm
