Question

I am trying to bypass this error: ItemNotFoundError: insufficient items with name u'No_Thanks' error by using try..except statement. However, I am getting another error saying: NameError: name 'ItemNotFoundError' is not defined. I am not sure why is this happening. Thanks. Here is the code that I am using

br = mechanize.Browser()
br.addheaders = [('User-agent', 'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1;Trident/5.0)')]
urls = "http://shop.o2.co.uk/mobile_phone/pay_monthly/init/Samsung/Galaxy_Ace_Purple"
r = br.open(urls)
page_child = br.response().read()
soup_child = BeautifulSoup(page_child)
contracts = [tag_c['value']for tag_c in soup_child.findAll('input', {"name": "tariff-duration"})]
data_usage = [tag_c['value']for tag_c in soup_child.findAll('input', {"name": "allowance"})]

for contract in contracts:
    if contract <>"Pay_and_Go":
        for data in data_usage:
            br.select_form('formDuration')
            br.form['tariff-duration']=[contract,]
            try:
                br.form['allowance']=[data,]
            except ItemNotFoundError:
                continue
            br.submit()
            page_child_child = br.response().read()
            soup_child_child = BeautifulSoup(page_child_child)
            items = soup_child_child.findAll('div', {"class": "n-pay-today"})

I’m guessing the exception is defined by mechanize. Try: except mechanize.ItemNotFoundError

It appears that this is correct after installing mechanize:

>>> import mechanize
>>> print mechanize.ItemNotFoundError
<class 'mechanize._form.ItemNotFoundError'>
>>> print mechanize.__version__
(0, 2, 5, None, None)
