    InSql= "SELECT  " % float
    f= csr.execute(InSql)
    nf = list(f) 

    NewL.append(str, float,ns, nf) 

Answer 1

Change your for loop to something like this:

for str_data, float_data in L:
    # str_data is the string, float_data is the Decimal object

Answer 2

Two ways:

First you could access the members of row:

#For string:
row[0]
#For the number:
row[1]

Or you specify your loop this way:

for (my_string, my_number) in l:
