How Do You Select Choices In A Form Using Python?

I'd like to know how to select options in a form that is formatted like Solution 1: Here are some basic usage examples to get you going:>>>import mechanize>>>br = mechanize.Browser()>>>br.open('http://www.w3schools.com/html/html_forms.asp')CopyForms have a name attribute; sometimes it's empty though:>>> [f.name for f in br.forms()] ['searchform', None, None, None, None, 'input0'] CopyForms have a sequence of controls; controls also have names:>>>forms = [f for f in br.forms()]>>>forms[1].controls[0].name 'firstname' >>>[c.name for c in forms[3].controls] ['sex'] CopyYou can get a listing of items in a control:>>> forms[3].controls[0].get_items() [<Item name='male'id=Nonetype='radio' name='sex' value='male'>, <Item name='female'id=Nonetype='radio' name='sex' value='female'>] CopyFor radio buttons, you have to make a single selection:>>>forms[3]['sex'] = ['male']CopyBut the selection has to be in a list:>>> forms[3]['sex'] = 'male' Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Python/2.6/site-packages/mechanize/_form.py", line 2782, in __setitem__ control.value = value File "/Library/Python/2.6/site-packages/mechanize/_form.py", line 1977, in __setattr__ self._set_value(value) File "/Library/Python/2.6/site-packages/mechanize/_form.py", line 1985, in _set_value raise TypeError("ListControl, must set a sequence") TypeError: ListControl, must set a sequence CopyFor check boxes you can make multiple selections:>>> [(c.name, c.get_items()) for c in forms[4].controls] [('vehicle', [<Item name='Bike'id=Nonetype='checkbox' name='vehicle' value='Bike'>, <Item name='Car'id=Nonetype='checkbox' name='vehicle' value='Car'>])] >>> forms[4]['vehicle'] = ['Bike', 'Car'] CopyYou can find more info here (link stolen from Matt Hempel :). Solution 2: When you say the page has multiple forms, do you mean there are multiple <form> elements on the page, or multiple form fields (like <select>)?The Mechanize docs for python sketch out how to select list items. Here's the sample they provide:# Controls that represent lists (checkbox, select and radio lists) are# ListControl instances. Their values are sequences of list item names.# They come in two flavours: single- and multiple-selection: form["favorite_cheese"] = ["brie"] # singleCopyIn your case, the code to select Value1 would look like this:form["FORM1"] = ["Value1"] Copy Share Post a Comment for "How Do You Select Choices In A Form Using Python?"
