[ TAG 165 ][03.09.2021] -Erfolgreich -IAP-20210601-20210722-1145 -RPRCSL_LOGGER

Ich beginne eine weitere Worksession um [03.10.2021][0630]. Für die Erstellung der Ordnerstrukturen habe ich mich für [pathlib]-Modul entschieden. Ich halte es für wesentlich effizienter.

In den nächsten Schritten möchte ich mich in die Python-Dokumentation einarbeiten.
