#51066 — How to tick checkboxes with the same name?

I faced a problem: to implement appropriate search program I need to tick few checkboxes which turned out to have the same name (name="a", id="a1","a2","a3","a4"). Set_input('a', True) does not work (I use Grab library), this command leads to the error "checkboxgroup must be set to a sequence". I don't understand what the sequence actually is, so I'm stuck with how to tick the checkboxes. It would be really great if someone would help me with how to handle this question. The code is available here:

Have you tried a[0], a[1], etc. for the names?

Instructions for solving your problem can be found here:

http://sscce.org/‎


Although it is written for Java, the same ideas will work for Python or 
any other programming language.

Have a read of that page, and if it isn't enough to solve your problem 
with "Grab" (whatever that is), feel free to come back.

For all but the most popular projects a url works wonders. I'm assuming 

http://grablib.org

If I were to guess:

set_input("a", [True, True, True, True])

but I don't see that form documented on page

http://docs.grablib.org/api/ext_form.html

If it doesn't work try

set_input_by_id(_"a1", True)
set_input_by_id(_"a2", True)

and so on.

Well, I have read the documentation, I guess the problem lies in somewhat different field. As long as I understand it refers to Checkboxgroup classes. As checkboxes of interest belong to some common group with the common name "a", they do have values different from "True" or "False" (probably a sequence?) and I should guess somehow what are the real ones. How to do this?

I took a quick look into the source, and it seems that grab has no notion of 
multiple inputs with the same name. My suggested workaround 

>> set_input_by_id(_"a1", True)

doesn't work because (among other things) the id is immediately translated 
into the name. I fear you have to construct the request manually or choose 
another library -- maybe mechanize (Python 2 only)?
