Well, you can get rid of the newline by ending with a comma, but it still
will insert spaces:

... print ch
...
a
b
c

... print ch,

I'm a big fan of hexlify:

Hi Everyone,
Thanks for all of your patience on this.
I finally got it to work.
Here is the completed test code showing what is going on.
Not cleaned up yet but it works for proof-of-concept purposes.

Hi Kent,
Sorry for causing so much trouble.
I am not married to either a single or multi-line solution one way or
another.
Just a solution that works.
Based on something by Danny Yoo provided, I had started with something like:

lol..
Glutton for punishment I guess.
I tried removing the last parentheses but I then get an error that two
arguments are passed when three are expected.

Hi all,
I tried:
output = open(r'e:\pycode\new_test.txt','wb')
for line in open(r'e:\pycode\out_test.txt','rb') :
output.write( re.sub(r'([^\w\s])', lambda s: chr(int(s.group(),

This generated the traceback:

Great!
Taking this a little further along, I wrote the converted file to a new
file using:

output = open(r'e:\pycode\out_test.txt','wb')
for line in open(r'e:\pycode\sigh.txt','rb') :

Yes, this is a feature of print, it always inserts a newline. To avoid
this, use sys.stdout.wr

Hi Everyone
I did a comparison of the output between the perl and python methodology.
They do basically the same thing but the perl form seems to be more "true"
The python method inserts extra blank lines after each hex value line.
For example:

In general I prefer to use string formatting to convert into hex
format.
print "%3X% % myValue

Or just

print.
