[Tutor] Space the final frontier!

[John Corry]

Dear All,

I am having difficulty removing white spaces from my file.  The file is 999
lines long and looks like the sample below:

001, new field,dial= 028 90 79 0154, dial=
002, borfiled, dial= 02890 618521, dial=
003, newcomp, dial=02890419689, dial=

The program, I am using to import the file does not like the spaces around
the numbers.  The number should look like the "dial=02890419689" in the
third line.  Thus the sample above should look like:

001,newfield,dial=02890790154,dial=
002,borfiled,dial=02890618521,dial=
003,newcomp,dial=02890419689,dial=

I have searched the tutor mailbag already and have picked up some good tips
on join, split and re but I can't seem to get it to work.

I am using the following code.

filename = "c:/test.txt"
import string
import os
import re
listy = []
input = open( filename, 'r')	#read access
for line in input.readlines():
    y = line
    listy.append(y)
    print listy
    x = listy.pop()

    re.sub(r'\s', '', x)
    print y,x

del input

It produces the output:

['001, new field,dial= 028 90 79 0154, dial=\n']
001, new field,dial= 028 90 79 0154, dial=
001, new field,dial= 028 90 79 0154, dial=

['002, borfiled, dial= 02890 618521, dial=\n']
002, borfiled, dial= 02890 618521, dial=
002, borfiled, dial= 02890 618521, dial=

['003, newcomp, dial=02890419689, dial=']
003, newcomp, dial=02890419689, dial= 003, newcomp, dial=02890419689, dial=

Any help would be greatly appreciated.

Regards,

John.
