Nice that Python can handle that, but this ultra-short syntax is not necessarily good for readability. I am more comfortable with more explicit syntax:
Dim x(11) As DWORD
ArraySet x()=120, 135, 345, 345, 1890, 12, 120, 12, 135, 712, 78, 120
ArraySort x(-) ; sort descending
For_ ct=0 To x(?)-1
Print Str$(x(ct)), " "
