reading directory from pc on rpi with python

[bmw318]

Hi,
I lnow there are Putty and Filezilla to read files on the RPI board and copy them on your PC but I want to do this in Python.
I want to write a program in Python to start activity (a measurement) on the RPI and retrieving the data, stored in the RPI, to my PC.

Are there any examples of doing that?

Thanks.

You can write to a file from python. See here..

You can store this file on your Pi, or on your PC (as a network share)

Share the folder from your PC, mount it as a samba/cifs share on your RPi.

Yes. https://docs.python.org/2/library/simplehttpserver.html
The simplehttpserver is a built-in module. Use your web browser to download files from the RPI (right click, save as).

It's very limited, only works one way, but is what you asked for.

Another option:

SSH can be used to run a nominated script or application on the remote system.

There are existing Python library modules that allow you to easily establish a secure ssh connection from within a Python script. I think paramiko is one, there may be others.

Glue those two ideas together and maybe you have the basis of another solution.

Thank you all. Will get in to this but I'm new in python.....

Hi,
do i have to install paramiko on both the raspberry pi AND my laptop/pc ?

You might find what you need in something like mqtt, or zeromq - messaging solutions.
What you describe does tend to look like you need an RPC style answer (or even just the simpler request/reply messaging).

SSH can appear a little "crude" with the need for authentication at each request (or the set up of security keys). You wouldn't have this issue with messaging.
