This is a choices settings with SelectField when you use an int, it works like this:

test_select = SelectField("Test", coerce=int, choices=[(0, "test0"), (1, "test1")], default=1)

or:

class TestForm(Form):
    test_select = SelectField("Test", coerce=int)

@app.route("/test")
def view_function():
    form = TestForm()
    form.test_select.choices = [(0, "test0"), (1, "test1")]
    form.test_select.default = 1
    form.process()
