for -- else: what was the motivation?

[Weatherby,Gerard]

As did I.

tree = ET.parse(lfile)
            for child in tree.getroot():
                if child.tag == 'server':
                    break
            else:
                raise ValueError(f"server tag not found in {lfile}")

I think there are other places I could be using it, but honestly I tend to forget it’s available.

  Just wrote code wherein I used "else"! This:

import locale
for name in( 'de', 'de_DE', 'deu_deu', 'deu', 'German', 'Deutsch' ):
    try: locale.setlocale( locale.LC_ALL, name ); break
    except locale.Error: pass
else: print( "Programm kann deutsche Schreibweise nicht einrichten." )
