如何选择单选按钮？

Question

我正在使用mechanize并试图从单选按钮列表中选择一个按钮。这个清单有五项。如何选择第一项？医生帮不了我。

>>> br.form
<ClientForm.HTMLForm instance at 0x9ac0d4c>
>>> print(br.form)
<form1 POST http://www.example.com application/x-www-form-urlencoded
<HiddenControl(DD=17010200) (readonly)>
<RadioControl(prodclass=[1, 2, 3, 4, 5])>
<SubmitControl(submit=text) (readonly)>>

Answer 1

It should be as simple as

br.form['prodclass'] = ['1']

我更喜欢比较冗长的：

br.form.set_value(['1'],name='prodclass')
