Glad it works, a couple of tweaks:
> filename = "a:/calllist.csv"
> filename2 = "c:/calllist.csv"
> import string
> import os
You don't use os or string so don't need to import them
> import re
And you don't really need re either, see below...
> listy = []
> input = open( filename, 'r') #read access
> input2 = open(filename2, 'w')
input is a builtin function so using it as a variable name could
cause confusion - input1 would be more consistent.
Although calling the second one output might be more
accurate?

you can just use the string replace method which for simple
replacements is faster than re and much less complex.
line = line.replace(' ','')
> y = line
> x = "\n"
> z = y + x
you don't really need all that
> input2.write(z)
input2.write(line + '\n')
is just as clear if not clearer! At least I think so! :-)
> del input

You should use close on a file not del.
input1.close()
input2.close()
