Selenium Python I have an Xpath using Ancestor axis can i convert this to a CSS selector - python-2.7

Question

I have an HTML page with a table of checkboxes. Each checkbox has a name.
In col1 is the checkbox. In col2 is the name.
I want to find the checkbox which has the name "Address"
I have managed to find it by using the following Xpath:
//table[#id="reporting_add_report_tab_manual_ct_vars_usn"]/tbody//tr//td//div[contains(text(), "Address")]//ancestor::tr[1]//input[#type="checkbox"]
I locate the column which contains the text "Address"
I then use ancestor to go up 1 row to it's parent of the current node and locate the checkbox
I would like to use CSS, can this xpath be converted to use the CSS locator?
CSS is quicker than Xpath to locate elements on the web page.
The HTML is:
<table id="reporting_add_report_tab_manual_ct_vars_usn" class="GJPPK2LBJE" cellspacing="0" __gwtcellbasedwidgetimpldispatchingfocus="true" __gwtcellbasedwidgetimpldispatchingblur="true">

Answer 1

If the order of the checkboxes is fixed you can use nth-of-type
input[type='checkbox']:nth-of-type(2)
This will find the second occurrence of input[type='checkbox'].
Or you can use nth-child.
table#reporting_add_report_tab_manual_ct_vars_usn tr:nth-child(2) td input
This finds the second tr in the table, in that row a td with an input.
