This is a short and practical tutorial that guides you on how to work with case-insensitive strings in Python and teaches how to use the str.lower, str.upper, and str.casefold methods.

This article shows how to communicate between Python and Dyalog APL through the use of sockets. We will use the module socket from Python and the Conga workspace from Dyalog.
