I now realize this is incorrect - sorry for my too quick reading of the python source.

Are you able to tell us what OS you are running on?  The part of the error "could not convert string to float:" is coming from the interpreter, but the rest of the message comes from the os/c compiler.

It almost sounds like it is a hosted machine and some system limit has been reached.  It is certainly an interesting error message!

Hey Keith,

The best I can do for string is the line from my original posting(client 
data, NDA, I'm sure you understand):

b1021384-6633-4756-b3e1-c36d34c1dfd2, clientname_001,Thu Dec  2 00:00:00
UTC 2010,2.96116E+11,0,0, Thu Dec  2 00:00:00 UTC 2010,577078067
20,15228831373,80966857300,


I will say that in the file there are 135 lines in the files. So it's 
not like there is a lot data to deal with. I wonder if I should move 
back to 2.7.

the code is still being worked on, so don't laugh to hard (constructive 
critisims are welcomed though) ;)
#!/usr/bin/python3

import sys
import re
from optparse import OptionParser

class client(object):
     def __init__(self, name, size):
         self.name = name
         self.size = float(size)
         self.east_coast = bool(re.search("_E", name))
         self.trial = bool(re.search("TR_", name))
         self.demo = bool(re.search("_Demo", name))
         self.zetta = bool(re.search("zetta|Zetta", name))

     def get_size(self):
         return str(self.size)

     def get_name(self):
         return str(self.name)


def read_file(filename):
     file_data = {}

     with open(filename, 'r') as f:
         for lines in f:
             split_lines = lines.split(',')
             file_data[split_lines[1]] = split_lines[3]

     return file_data

if __name__ == "__main__":

     file1_clients = {}
     file2_clients = {}
     file1_class_clients = []
     file2_class_clients = []

     usage = "%prog [options]"
     parser = OptionParser(usage=usage)
     parser.add_option("-f", "--first", dest="first",
         help="Older file first, builds table from here.")
     parser.add_option("-s", "--second", dest="second",
         help="New file, used for calculating the difference.")

     (options,args) = parser.parse_args()

     if not options.first or not options.second:
         print("The file argument (-f) is nessacary to run this program.\n")
         parser.print_help()
         sys.exit(1)

     file1_clients = read_file(options.first)
     file2_clients = read_file(options.second)

     for x,v in file1_clients.items():
         file1_class_clients.append(client(x,v))

     for x,v in file2_clients.items():
         file2_class_clients.append(client(x,v))

     for x in file1_class_clients:
         print(x.get_name() + ":" + x.get_size())
