[Pyparsing] pyparsing floats - still stuck

[Donn I. <don...@gm...>]

Hi,
Still stuck. I am having trouble getting a float out of the parsed String.
Here's a sample:

from pyparsing import *
dot = Literal(".")
float = Combine(Optional("-") + Word(nums) + dot + Word(nums))
command = oneOf("M L C Z")
comma = Literal(",").suppress()
couple = Group(float + comma + float)
phrase = OneOrMore(command + Group(OneOrMore(couple) ) ) + Optional(command)

d2="""
M 269.78326 , 381.27104
C 368.52151 , 424.27023 
 90.593578 , -18.581883
 90.027729 , 129.28708
C 89.461878 , 277.15604
 171.04501 , 338.27184
 269.78326 , 381.27104
 z """

pl = phrase.parseString(d2.upper())

for t in pl:
    for i in t:
        if len(i) == 1: print i
        if len(i)>1:
            for si in i: 
                print "si",si,
                print "type(si):", type(si)
                print " float(si):", float(si)

I need those values to be floats. What am I doing dumb?
