Ok, so how about if I change the last example to:
"""A simple example that can retrieve an age from the database"""
def getAge(self, name):
# Define the query
sql = """SELECT Age FROM People WHERE name = ?"""
# Run the query, and set a callback to run when done
return self.runOperation(sql, name)
def gotAge(resultlist, name):
"""Callback for handling the result of the query"""
age = resultlist # First field of first record
print "%s is %d years old" % (name, age)
db = MyDatabase(dbpool)
# These will *not* block. Hooray!
If this looks sane to you, I'll update the example and the surrounding text at

Actually, it was suggested to me that I should be more explicit with my
licencing of that document. I haven't had time to probably examine
documentation licences, so I'll just state this instead: I donate the copyright
to that tutorial to the Twisted developers (i.e. Twisted Matrix Laboratories).
Basically, do what you like, I won't sue :)
