Hi,
A quick one...
How do I split a string like "Hans" into a list of characters
['H','a','n','s']?
Note that there are no spaces in the original string.
Str.split() without any arguments looks for whitespace as splitting
character. So, this doesn't serve the purpose.
And str.split("") app

It's a sequence of bytes and you've asked Python to print its
string representation. So where the bytes are unprintable
ascii codes it shows you the hex, thus:

Its just indexing the list returned by struct.unpack(),
specifically extracting tghe first element.

You need to use COM to do it, Mark Hammonds book "Python Programming

Hi Gang,
Thanks to Danny Yoo for a great answer. The answer given is a little
advanced so I have to ask the following follow-up.
What does it mean when you write the [0] after the return statement?
e.g. return struct.unpack("!h", bytes)[0]

it: (I haven't officially tested this code for bugs, but I believe it
is correct.)

They both start thread
Well, I don't know how it works on Windows, but on UNIX, if you want to
create a deamon able to stay alive when you deconnect you "just" have to
catch the HUP signal and ... do nothing of it :) By default this signal
exit the application.
You have two ways of doing so :

You will need to create a new file. Basically you need to:
Read the current file into a list or string.
Rename the old file (foo.ba
Ok, better question.
Are these two equivalent:

1)
thread = Thread(target=run_server, args=(server,))
#thread.setDaemon(True)
thread.start()
2)
server.listen(1)
thread.start_new_thread(run_server,(server,))
So that I can uncomment the setDaemon() method?

Hi all,
I want to write to a text file with a timestamp, but I want to newest entry at the top. So I want to insert the next entry to the file at the beginning.
I can create and append to a file and then the latest entry is at the bottom.
Any ideas how this is done please?
