python – Why does “return list.sort()” return None, not the list? – Stack Overflow

Posted by jpluimers on 2020/01/02

list.sort sorts the list in place, i.e. it doesn’t return a new list. Just write

newList.sort()
return newList

The above answer is goden as performing return list.sort() bytes me often, because Python is usually an environment using the functional approach.

GitHub – Libaud/POLCLVCLISO: Pascal Object LCL and VCL ISO standards implementation for CodeTyphon, Delphi, Lazarus

Posted by jpluimers on 2020/01/02

For my link archive: GitHub – Libaud/POLCLVCLISO: Pascal Object LCL and VCL ISO standards implementation for CodeTyphon, Delphi, Lazarus

It implements these standards:

  • ISO standard 3166-1, 3166-2, 3166-3 implementation
    • (all part of the ISO 3166 – Wikipedia that “defines codes for the names of countries, dependent territories, special areas of geographical interest, and their principal subdivisions)”
  • ISO standard 4217 implementation
    • ISO 4217 – Wikipedia  “delineates currency designators, country codes (alpha and numeric)” where the country codes are the same as in ISO 3166
  • ITU E.164 standard implementation
    • E.164 – Wikipedia “E.164 defines a general format for international telephone numbers. Plan-conforming numbers are limited to a maximum of 15 digits, excluding the international call prefix.”

A library like this needs monitoring the standards changes, so hopefully Libaud will do that.

Some of my posts related to ISO 3166 are below.
