For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Python network programming - new FTP and socket level examples

These days, it's the exception rather than the rule to write low level network code within your applications - and during today's Intermediate Python course, I wrote an example showing an FTP connection to retrieve data using ftplib. The first example is [here] - grabbing a file, saving it locally via a callback.

A second version, using a thread to allow the FTP connection to be running while the main program is getting on with something else, is [here].

If you do need to program a socket directly, yes, you can do so. I've revised / refreshed myself into that - [here] is a demonstration from first principles of picking up a header from a web server. Lots of extra checking to do really, but the examples show the principles and you can build from there.
