Antwort
Für Projekte, wie Chat's usw. würde ich Python benutzen. Visual Basic ist auch nicht wirklich empfehlenswert. Für wirklich große Projekte, wie z.B. 3D Spiele würde ich an deiner Stelle C# verwenden.
Ich habe auch mal einen Chat-Client und -Server in Python geschrieben. Es ist teilweise allerdings noch etwas verbuggt. Ich würde es nur als Vorlage benutzen, da ich selber festgestellt habe, dass manche Dinge etwas unpraktisch implementiert wurden. Naja, wie auch immer.
