How do I create functions that will replicate the diagrams above with lists that reference each other? My current code is:

shape_alpha() abc" -17 123 456 shape_bravo() "whoa" 'excellent "bogus" "righteous" "rufus shape_charlie(argi) None arg1 arg1 shape_delta(argi, arg2) arg1 arg1 arg1 arg2 arg2 arg1 arg2 arg2 30 shape_echo (argi, arg2, arg3) arg1 arg2 ara3 def shape_alpha(): return [[10, 'abc', 'jkl,40'],[[1.1,-17],[123,456]]], def shape_bravo(): list1 = ['bogus', 'righteous'] return [[['woah', 'excellent'],list1],[listi, 'rufus']], def shape_charlieCargl): return [[[[None, arg1], argi], arg1], arg1] def shape_delta(argi, arg2): return [argi, arg2, Carg1, [arg1, arg2, [arg1, arg2],30],20, arg2],10] def shape_echoCargi, arg2, arg3): list1 = [list2, arg1] list2 = [list3, arg2] list3 = [listi, arg3]
