Thanks Evgeny, you cannot execute my jupyter notebooks on Azure cloud and I think you have to login first in order to view them. In any case my CacheORM module is dependent on intersys.pythonbind module. One has to install this first and verify that it works then start playing with my demos. I wrote guidelines about installation in Github README file.

Hi Robert, I must acknowledge that I have been inspired from your post and the comments we exchanged there ;-)

Thanks John the link is now fixed.

Good morning Robert,  based on the piece of code you sent me for a Python TCP socket server I made these SocketReceiver, SocketSender  classes for Python 3 so now it is super easy for anyone to run a simple TCP socket communication test on two Python consoles.

Then I wrote this ClassMethod 

ClassMethod SendMessage(msg As %String = "", port As %Integer)
{
set tcp="|TCP|"_port
    open tcp:("127.0.0.1":port:"PSTE"):1 else  quit
    use tcp
    write msg,!
    write !!
    // close tcp
    Quit
}

The only problem here is the 'close tcp' statement that closes the listener which has been set at a Python console and I commented this out  (I am sure there can be a better way). 
Finally I opened two python consoles and successfully tested the whole thing
Case is closed, hope this will be useful for others too, thank you again for your assistance and guidance

Done, thanks for the lesson Robert ;-) I voted your comments and I verified that this method works for two Cache terminals, one listener, one sender. But I do not have a clue how this can be done in the same or different Python consoles and this way such an answer to my question will be complete.

Hi Robert, thanks for the update, let's try to sort this out in Cache Terminal then. I have added an extra write !! statement before the close tcp. Then I opened a terminal switched to SAMPLES namespace and entered the following commands

    set person = ##class(Samples.Person).%OpenId(1)

    w person.Name

    do person.PrintPersonTCP()

    set tcp="|TCP|4200"

    open tcp:(:4200):1 write $s($t:"OK",1:"failed"),!

The result is OK

But the next line of your code

     for line=1:1 use tcp read text use 0 write line,?5,text,!

just made the cursor blink in the next line without returning anything

Hi Robert, thanks for posting an answer, I added an extra PrintPersonTCP() at Sample.Person with your code and then I called the method from Cache Python binding package but it did not print anything on IPython console.

Hi Rubens, the only reason I need this redirection is for sending messages to the Python console for debugging, introspection purposes NOT for sending data. CachePython Query and CachePython Object packages can handle this automatically. Therefore in general I am looking for something simple, like this method Robert wrote above. Alternatively if it's too complicate, I am thinking of opening a stream and write a log there.
