Hi,

a Python program needs to receive "z" from pd.

In pd I generate "z" values by moving a slider.
The Python code is already ready to receive z.

What is the correct patch to do this?
Thanks,
a.

pd2py.pd

Simply connect the slider to the sender.

Ok, but I left the blank space between slider and netsend because I don't know how to write the variable z that python expects. Something like "send z $1".

@atux You can try that....... pd2py_v2.pd
Does it work?
If not then post your Python code and someone will tell you why not.

Thanks, it works fine.
But in order for python to receive the values ​​correctly, I had to remove "-b" from [netsend -u -b].
These are some values ​​received from pd:

$ python3 py_from_pd.py
Socket bind completed on 127.0.0.1:9999. Waiting for messages...
Raw data received from ('127.0.0.1', 51903): b'z 0.5;\n'
Decoded message: z 0.5;
Value of z: 0.5
Raw data received from ('127.0.0.1', 51903): b'z 0.509868;\n'
Decoded message: z 0.509868;
Value of z: 0.509868
Raw data received from ('127.0.0.1', 51903): b'z 0.519737;\n'
Decoded message: z 0.519737;

It seems good to me.
I attach both files, so it can be useful:
py_from_pd.py
pd2py_v2.pd

Thank you,
a.

[netsend] help for the [send( message says "same as list" so you can also do

[hslider]
|
[list prepend z]
|
[netsend]

Yes, that's how it works too.
pd2py_v3.pd
For less computational effort, is one preferable to the other, or are they equivalent?
Thank you,
a.

I think it's easier to dynamically upgrade the variable name with the [list prepend] right inlet.
