Well House Consultants specialise in training courses in
Tcl/Tk, Expect,
Python,
Perl,
PHP, and
MySQL. We run
Private Courses throughout the UK (and beyond for longer courses), and
Public Courses at our training centre in Melksham, Wiltshire, England.
It's surprisingly cost effective to come on our public courses -
even if
you live in a different
country or continent to us.
We have a technical library of over 600 books on the subjects on which we teach.
These books are available for reference at our training centre. Also
available is the Opentalk
Forum for discussion of technical questions.
