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.
Splitting Pythons in Bradford

Python supports two split functions methods to explode a string into a list of substrings. There's one in the default class that works on a string, and there's another in the re (Regular Expression) class.

Splitting at a string works very will if you've got a fixed delimiter, typically in a machine generated file of data. You write
inputstring.split(separator)
however, with data that's entered by a user and may well contain multiple spaces as the separator, you would be better advised to write
regex.split(inputstring)
and, yes, the parameters are indeed the other way around.

Here's the result of splitting an address which had multiple spaces in in between the company hame and town, using the string and re classes:
['Techsputer', 'Training,', '', 'Bradford', 'on', 'Avon']
['Techsputer', 'Training,', 'Bradford', 'on', 'Avon']

and you can see the full source code here
