### Mit Python-*Enumerationen* arbeiten { #working-with-python-enumerations }

Der *Pfad-Parameter* wird ein *<abbr title="Member – Mitglied: Einer der möglichen Werte einer Enumeration">Member</abbr> einer Enumeration* sein.

#### *Enumeration-Member* vergleichen { #compare-enumeration-members }

Sie können ihn mit einem Member Ihrer Enumeration `ModelName` vergleichen:
