Code:
for subdir, dirs, files in os.walk('var/www/html/data/customer/log'):
    for file in files:
        regexp = re.findall(r"10.7.0.145", open(file, "r").read())
        print " Here is whats inside of %s = %s" % (regexp,file)
   ....:         
  Here is whats inside of [] = file3
 Here is whats inside of [] = file6
 Here is whats inside of [] = file7
 Here is whats inside of [] = file1
 Here is whats inside of ['10.7.0.145'] = file9
 Here is whats inside of [] = file5
 Here is whats inside of [] = file8
 Here is whats inside of [] = file10
 Here is whats inside of [] = file2
 Here is whats inside of [] = file4

I made some progress but cant figure out how to just print the file containing the regular expression. So it prints something like this:
Code:
Here is whats inside of ['10.7.0.145'] = file9

only

I figured it out with some help. re.findall returns a list. So I need to only print
Code:
 [0]

which gets the first (and only) item in matches. The if-statement in place, the print line will only be run if matches is non-empty.

Code:
for subdir, dirs, files in os.walk('.'):
    for file in files:
       matches = re.findall(r"10.7.0.145", open(file).read())
       if matches:
           print " I found what I was looking for %s = %s" % (file,matches[0])

returns:
Code:
Here is whats inside of file9 = 10.7.0.145

objective complete.

wildmat

WILDMAT(3)						     Library Functions Manual							WILDMAT(3)

NAME

       wildmat - perform shell-style wildcard matching

SYNOPSIS

       int
       wildmat(text, pattern)
	   char       *text;
	   char       *pattern;

DESCRIPTION

       Wildmat	is  part  of libinn (3).  Wildmat compares the text against the pattern and returns non-zero if the pattern matches the text.  The
       pattern is interpreted according to rules similar to shell filename wildcards, and not as a full regular expression such as  those  handled
       by the grep(1) family of programs or the regex(3) or regexp(3) set of routines.

       The pattern is interpreted as follows:

       x     Turns  off the special meaning of x and matches it directly; this is used mostly before a question mark or asterisk, and is not spe-
	      cial inside square brackets.

       ?      Matches any single character.

       *      Matches any sequence of zero or more characters.

       [x...y]
	      Matches any single character specified by the set x...y.	A minus sign may be used to indicate a	range  of  characters.	 That  is,
	      [0-5abc] is a shorthand for [012345abc].	More than one range may appear inside a character set; [0-9a-zA-Z._] matches almost all of
	      the legal characters for a host name.  The close bracket, ], may be used if it is the first character in the set.  The  minus  sign,
	      -, may be used if it is either the first or last character in the set.

       [^x...y]
	      This  matches any character not in the set x...y, which is interpreted as described above.  For example, [^]-] matches any character
	      other than a close bracket or minus sign.

HISTORY

       Written by Rich $alz <rsalz@uunet.uu.net> in 1986, and posted to Usenet several times since then,  most	notably  in  comp.sources.misc	in
       March, 1991.

       Lars Mathiesen <thorinn@diku.dk> enhanced the multi-asterisk failure mode in early 1991.

       Rich and Lars increased the efficiency of star patterns and reposted it to comp.sources.misc in April, 1991.

       Robert Elz <kre@munnari.oz.au> added minus sign and close bracket handling in June, 1991.
