sorted_robust

(function from pyomo.common.sorting)

pyomo.common.sorting.sorted_robust(iterable, key=None, reverse=False)

Utility to sort an arbitrary iterable.

This returns the sorted(arg) in a consistent order by first trying the standard sort() function, and if that fails (for example with mixed-type Sets in Python3), use the _robust_sort_keyfcn utility (above) to generate sortable keys.

Parameters:

• iterable (iterable) – the source of items to sort

• key (function) – a function of one argument that is used to extract the comparison key from each element in iterable

• reverse (bool) – if True, the iterable is sorted as if each comparison was reversed.

Return type:

list
