Putting a checkbox using python mechanization

Question

I want to fill out a form using python mechanization. the form is as follows:

<POST https://10.20.254.39/cloud_computing/vmuser/migrate_vm/cli multipart/form-data <TextControl(vm=cli)> <TextControl(chost=10.20.14.39)> <SelectControl(dhost=[*, 28, 27])> <CheckboxControl(live=[on])> <CheckboxControl(undefinesource=[on])> <CheckboxControl(suspend=[on])> <SubmitControl(<None>=Submit) (readonly)> <HiddenControl(_formkey=85819e5a-02bb-42c8-891f-3ddac485438b) (readonly)> <HiddenControl(_formname=migrate_create) (readonly)>> 

How to set the value of live or undefinesource (check box) to True (checked) or False (untick) The live and undefinsource elements:

 >>> print br.form.controls[4].get_items() [<Item name='on' id='migrate_undefinesource' checked='checked' name='undefinesource' type='checkbox' id='migrate_undefinesource' value='on' class='boolean'>] >>> print br.form.controls[3].get_items() [<Item name='on' id='migrate_live' checked='checked' name='live' type='checkbox' id='migrate_live' value='on' class='boolean'>] 

Answer 1

One of the ways I did this is by

 br.find_control("live").items[0].selected=True
