# To run on all hits:    
#for i in b:
#    hitid=i.HITId
#    updateid(hitid)

# to search for a specific hit:
# ["%s -- %s -- %s -- %s " % (i,x.Title,x.CreationTime,x.NumberOfAssignmentsAvailable) for i,x in enumerate(b)]
# Then, for whatever number in the list:
#updateid(b[0].HITId)

# use this to make sure that your search string will uniquely identify the correct qualification (you could use this to manually get the qualification id and put it in the updateid method above:
# print ["%(name)s %(id)s"  % {"name":x.Name,"id":x.QualificationTypeId} for x in mturk.search_qualification_types('prior')]
