list of dict . [{'id': 19, 'success': true, 'title': u'apple'}, {'id': 19, 'success': false, 'title': u'some other '}, {'id': 19, 'success': false, 'title': u'dont know'}] i want count of how many dict have success true . i have tried, len(filter(lambda x: x, [i['success'] in s])) how can make more elegant using pythonic way ? you use sum() add boolean values; true 1 in numeric context, false 0: sum(d['success'] d in s) this works because python bool type subclass of int , historic reasons. if wanted make explicit, use conditional expression, readability not improved in opinion: sum(1 if d['success'] else 0 d in s)
