Wrong !
see:

In [6]: 'Rita' and 'Sue' and 'Bob' in ['Bob']
Out[6]: True

This second piece of code searches list for the sequence 
['Rita','Sue','Bob'] in this order and without inserts.
It can be rewritten in a more pythonic way :

for i in range(len(l)):
     if l[i:i+3] == ['Rita','Sue','Bob']:
         print 'They were found'
         break
else:
     print 'They were not in the list'
