python - Unable to set the value of a SelectControl element -


i trying machine-parsable bus schedule data submitting form mechanize.

however, stymied mechanize syntax setting 

import mechanize br = mechanize.browser() br.open("http://www.planibus.sto.ca/hastinfoweb/starttimetableform.aspx") br.select_form(name="timetablequeryform") br["routedirectiondynamiccombobox$combobox_input"] = "10 ottawa" # works fine, it's textcontrol br["datepicker$daysdropdownlist"] = ["3"] # selectcontrol ### mechanize._form.itemnotfounderror: insufficient items name '3'

mechanize._form.itemnotfounderror: insufficient items name '3' looks needs list, when enter more 1 item in list (which makes little sense, given date picker) get:

mechanize._form.itemcounterror: single selection list, must set sequence of length 0 or 1

i thought original ["3"] sequence of length 1?

thanks attention. i'm missing obvious...

edit: note '3' above 1 value, , web site allows values next 2 weeks in ui, depending on when see this, list of allowable values change. substitute '3' 1 of allowable values... still doesn't work me...

3 isn't 1 of available select options, options see are

<option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> <option value="11">11</option> <option value="12">12</option> <option value="13">13</option> <option value="14">14</option> <option value="15">15</option> <option value="16">16</option> <option value="17">17</option> <option value="18">18</option>

so try br["datepicker$daysdropdownlist"] = ["4"] , code should work.

edit: i've tried looking @ page in question mechanize, try this

import mechanize br = mechanize.browser() br.open("http://www.planibus.sto.ca/hastinfoweb/starttimetableform.aspx") br.select_form(name="timetablequeryform") select = br.form.controls[8] # datepicker$daysdropdownlist select.possible_items() >>> []

there aren't options, imagine javascript used populate them after page has loaded. unfortunatly mechanize doesn't support javascript, try using selenium webdriver scrape data need.
