The common idiom for this is called decorate-sort-undecorate.
unsorted_list = [
{'Title': 'ABC',
'from_datetime': DateTime('2006/04/25 12:45:00 GMT+2')},
{'Title': 'DEF',
'from_datetime': DateTime('2006/04/18 12:45:00 GMT+2')},
{'Title': 'GHI',
'from_datetime': DateTime('2006/03/10 12:45:00 GMT+2')}]
decorated_list = [(d['from_datetime'], d) for d in unsorted_list]
decorated_list.sort()
sorted_list = [t[1] for t in decorated_list]
