Create nested python dictionary

I am using the python code below to extract some values from an excel spreadsheet and then push them to an html page for further processing. I would like to modify the code below so that I can add additional values against each task, any help

the code below does spit out the following:

{'line items': {'AMS Upgrade': '30667', 'BMS works': '35722'}}

How can I revise the code below so that I can add 2 more values against each task i.e. AMS Upgrade and BMS works and get the likes of (note the structure below could be wrong)

{'line items': {'AMS Upgrade': {'30667','100%', '25799'}},{'BMS works': {'10667','10%', '3572'}} }

Code:

book = xlrd.open_workbook("Example - supporting doc.xls")
first_sheet = book.sheet_by_index(-1)
nested_dict = {}
nested_dict["line items"] = {}

for i in range(21,175):
    Line_items = first_sheet.row_slice(rowx=i, start_colx=2, end_colx=8)

    if str(Line_items[0].value) and str(Line_items[1].value):
        if not Line_items[5].value ==0 : 
            nested_dict["line items"].update({str(Line_items[0].value) : str(Line_items[1].value)})

print  nested_dict
print json.dumps(nested_dict)

*** as requested see excel extract below

In Python, each key of a dict can only be associated with a single value. However that single value can be a dict, list, set, etc that holds many values.

You will need to decide the type to use for the value associated with the 'AMS Upgrade' key, if you want it to hold multiple values like '30667','10%', '222'.

Note: what you have written:

{'30667','100%', '25799'}

Is a set literal in Python.
