HTML select options from python list - adi.6194 - Oct-20-2016 I'm writing a python-cgi script to setup a Hadoop cluster. I want to create an HTML select dropdown where the options are taken from a python list. Is this possible?? I've looked around a lot. Couldn't find any proper answer to this. So far, I'm only using a single .cgi file which has both the html code as well as the python code in it. I really need to find an answer to this. I'd appreciate any help at all. Thanks. The options i need are IP addresses. I have a function which stores the IP addresses into a python list.

RE: HTML select options from python list - adi.6194 - Oct-20-2016 This is giving me an error OPTIONS undefined on the " OPTIONS=html_list " line This is the error. (I'm using optionlist instead of html_list) OPTIONS undefined, optionlist = '<option value=192.168.100.103>192.168.100.103</option>' <type 'exceptions.KeyError'>: ' \n\t\t\tbackground' args = (' \n\t\t\tbackground',) message = ' \n\t\t\tbackground' RE: HTML select options from python list - metulburr - Oct-20-2016 (Oct-20-2016, 09:08 AM)adi.6194 Wrote: This is giving me an error OPTIONS undefined on the " OPTIONS=html_list " lineToo tired at the moment. But you dont really need the OPTIONS at all. This is by keyword, and you can use by position. http://python-forum.io/Thread-string-format-and-string-expressions '<select> {} </select>'.format(optionlist) RE: HTML select options from python list - adi.6194 - Oct-20-2016 Wow. Thank you so much. This is amazing. |
