如何选择单选按钮？

Question

我正在使用mechanize,我正在尝试从单选按钮列表中选择一个按钮.此列表有5个项目.如何选择第一项？文档没有帮助我.

>>> 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

它应该如此简单

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

我更喜欢更详细的:

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