from zope.schema.vocabulary import SimpleTerm, SimpleVocabulary states = ('Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California', 'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii', 'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana', 'Maine', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota', 'Mississippi', 'Missouri', 'Montana', 'Nebraska', 'Nevada', 'New Hampshire', 'New Jersey', 'New Mexico', 'New York', 'North Carolina', 'North Dakota', 'Ohio', 'Oklahoma', 'Oregon', 'Pennsylvania', 'Rhode Island', 'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont', 'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming') state_terms = [SimpleTerm(value=state, title=state) for state in states] state_vocab = SimpleVocabulary(state_terms)In this example, we define a tuple of all 50 state names and then use a list comprehension to create a SimpleTerm for each state with the value and title set to the state name. We then create a SimpleVocabulary using the list of SimpleTerms as the terms for the vocabulary. Another example use case could be for a dropdown menu in a web form. The SimpleVocabulary could be used to define the options available for the dropdown, with each SimpleTerm representing one option. Overall, the zope.schema.vocabulary package provides a useful set of tools for creating and managing vocabularies in Python applications.
