pass python list to ladon using suds

I want to send a python list to my ladon service. Consider the following python list

lst_col_title = [(1, 'Column1', 10, 'L'),(2, 'Column2', 15, 'L'),(3, 'Column3', 15, 'L'),(4, 'Column4', 10, 'L'),(5, 'Column5', 10, 'L')]

Is their any possible way to send this kind of list to ladon services using suds.

EDIT Actually I want to send the following python variables to a ladon service using suds

    str_report_name = 'OPENING BALANCE REPORT'
    str_report_format = 'GENERAL'
    lst_main_heading = [('<w><h><b><ds>NAME TRAVEL & TOURISM</ds></b></h></w>', 1), ('<p5><b>     <b></p5>', 2), ('<b><p2>P.O BOX 3000, JEDDAH 12345, KSA, Phone: 02 6845455</p2></b>', 3), ('<b><p2>Email: info@nametravel.com, Fax: 02 6873455, C.R.No: </p2></b>', 4), ('', 5)]
    lst_header = []
    lst_report_header = [['', 'CREDIT NOTE', '', '<u><b><w>'], ['', '', '', ''], ['', 'No: RF/1', '', '<b>'], ['To, CASH KAAU (942)', '', 'Date: 01/01/2011', '<b>'], ['    P.O. Box No. 3263,DOHA,QATAR', '', 'Code: C022      ', '<b>'], ['    Tel: +91 9945 4561 45, Fax: +21 7894 7894', '', '', '<b>'], ['    E-Mail: cashkaau123@gmail.com', '', '', '<b>'], ['', '', '', ''], ['Please note that we have CREDITED your account with following details.', '', '', '']]
    lst_page_header = []
    lst_footer = []
    lst_page_footer = []
    lst_report_footer = [['Two Thousand Two Hundred Seventeen Saudi Riyal Only ', '', '2217.00', '<b>'], ['', '', '', ''], ['Accountant', 'Created By:ADMIN', 'Manager', ''], ['', '', '', ''], ['Signature', '', '', '']]
    lst_report_data = [('', '', '', '', ''), (1, '065-9778821549', 'ABOUNASEF/SEHAM KAMEL MRS', 'JED/CAI/JED', '2584.00'), ('', '', '<i>Less</i>: Cancellation Fee', '', '367.00'), ('', '', '', '', ''), ('', 'THIS IS TO CHECK THE NARRATION PRINTING THIS IS TO CHECK THE NARRATION PRINTING THIS IS TO CHECK THE NARR<i>', '', '', '')]
    bln_show_column_heading = True
    lst_col_title = [(1, 'Column1', 10, 'L'),(2, 'Column2', 15, 'L'),(3, 'Column3', 15, 'L'),(4, 'Column4', 10, 'L'),(5, 'Column5', 10, 'L')]

This is my ladon service

@ladonize(str,str,[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING], rtype=str)
def generate_pdf_print(self, str_report_name,str_report_format,lst_main_heading, lst_header, lst_report_header, lst_page_header, lst_footer, lst_report_footer, lst_page_footer, lst_report_data, bln_show_column_heading, lst_col_title, **args):

But [PORTABLE_STRING] will not do what I want.

As I am new to web services, I have no idea how to deal with thease type of complex python types.

UPDATE

I have created a new ladon type for

    lst_col_title = [(1, 'Column1', 10, 'L'),(2, 'Column2', 15, 'L'),(3, 'Column3', 15, 'L'),(4, 'Column4', 10, 'L'),(5, 'Column5', 10, 'L')]

as:

class Table(LadonType):
    slno = int
    col_title = PORTABLE_STRING
    col_size = int
    col_align = PORTABLE_STRING

and modified the @ladonize as,

@ladonize(str,str,[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[PORTABLE_STRING],[ Table ], rtype=str)

Is this a right way? It raises an error for me

' Server raised fault: '
classname: <class 'AccountEngine.Table'>
Dictionary expected for prime_dict got "<type 'unicode'>" of value "1"'

Solution

I have solved this problem, by converting each list as string.

self.generate_pdf_file(str_report_name,
                str_report_format,
                str(lst_main_heading),
                str(lst_header),
                str(lst_report_header),
                str(lst_page_header),
                str(lst_footer),
                str(lst_report_footer),
                str(lst_page_footer),
                str(lst_report_data),
                bln_show_column_heading,
                str(lst_col_title))

Now my @ladonize looks like:

@ladonize(str,str,str,str,str,str,str,str,str,str,str,str, rtype=str)
def generate_pdf_print(self, str_report_name,str_report_format,lst_main_heading, lst_header, lst_report_header, lst_page_header, lst_footer, lst_report_footer, lst_page_footer, lst_report_data, bln_show_column_heading, lst_col_title, **args):

And reverted those valuesusing eval as follows:

def generate_pdf_print(self,db,
                            str_report_name = 'OPENING BALANCE REPORT',
                            str_report_format = 'GENERAL',
                            lst_main_heading = [],
                            lst_header = [],
                            lst_report_header = [],
                            lst_page_header = [],
                            lst_footer = [],
                            lst_report_footer = [],
                            lst_page_footer = [],
                            lst_report_data = [],
                            bln_show_column_heading = True,
                            lst_col_title = [],
                            int_count_blocks_of_data_in_print = 1,
                            str_pdf_theme = 'Default'
                            ):

    lst_main_heading = eval(lst_main_heading) 
    lst_header = eval(lst_header)
    lst_report_header = eval(lst_report_header) 
    lst_page_header = eval(lst_page_header) 
    lst_footer = eval(lst_footer)
    lst_page_footer = eval(lst_page_footer)
    lst_report_footer = eval(lst_report_footer) 
    lst_report_data = eval(lst_report_data) 
    bln_show_column_heading = True
    lst_col_title = eval(lst_col_title)
