That's what the fancier __init__() at the end of the article[1] is for :)

Here's the tl;dr of a real-world example[2]:

    query = Query().SELECT(...).WHERE(...)
    for subtags in tags:
        tag_query = BaseQuery({'(': [], ')': ['']}, {'(': 'OR'})
        tag_add = partial(tag_query.add, '(')
        for subtag in subtags:
            tag_add(subtag)
        query.WHERE(str(tag_query))

It can be shortened by making a special subclass, but I only needed this once or twice so I didn't bother yet:

    for subtags in tags:
        tag_query = QList('OR')
        for subtag in subtags:
            tag_query.append(subtag)
        query.WHERE(str(tag_query))
