Ich benutze Gc-Modul, um ein Leck zu debuggen.Ist das ein Speicherleck?
Es ist ein GUI-Programm und ich habe diese Funktion an eine Taste angeschlossen.
Ich habe set debug mehr auf gc.SAVE_ALL
> gc.collect()
>
> print gc.garbage
und dies ist der Ausgang

Die gc.garbage Liste viele Elemente hat. Bedeutet das, dass die Objekte in gc.garbage undicht sind oder gesammelt wurden oder gesammelt werden?
