length of a uuid-field

[Johann Spies]

In the book the examples for using uuid as a unique field in a table shows:

Field('uuid', length=64, default=lambda:str(uuid.uuid4())),


I have been using this for a long time without really thinking about it.  The uuid-strings generated has the length of 36.  

So why the 'length=64'?

Johann

It is an example. You can change it.
