我一定错过了一些东西，但是我在找出最大的值并使用csv.DictReader()函数打印它们时遇到了问题。
csv文件是类似的(我已经删除了字段以及行，因为这些格式的行太宽)：
traverse;damage;hull_front;turret_back;penetration;full_name;tier;hull_back;turret_sides;type;hull_sides;turret_front
38;30;18;16;32;Light Tank MS-1;1;16;16;Light Tank;16;18
40;30;13;13;32;Light Tank BT-2;2;13;13;Light Tank;13;15
55;36;15;15;34;Light Tank T-26;2;15;15;Light Tank;15;15(希望我得到了所有的领域，我不得不使用原始文件剪切。)
我读了这个文件
tanks = csv.DictReader(open('tanks.csv', 'r'), delimiter = ';')但是当我试图找出例如哪一行在哪个列中具有最大的价值，我似乎无法通过字典来阅读。我的尝试看起来像这样：
def top_values(tanks):
tank = list(itertools.islice(tanks,1,2))
best_tanks = dict({'turret_front':tank, 'turret_sides':tank, 'turret_back':tank,
'hull_front':tank, 'hull_sides':tank, 'hull_back':tank,
'penetration':tank, 'damage':tank, 'traverse':tank})
fields = ['turret_front', 'turret_sides', 'turret_back',
'hull_front', 'hull_sides', 'hull_back',
'penetration', 'damage', 'traverse']
for tank in tanks:
for field in fields:
if tank[field] > best_tanks[field][field]:
best_tanks[field] = tank
print "Best tanks by values:\n"
for field in fields:
tank = best_tanks[field]
print field + ": " + tank['full_name'] + "(" + tank[field] + ")"但我明白了
Traceback (most recent call last):
File "./wotalyzer.py", line 102, in
main(sys.argv[1:])
File "./wotalyzer.py", line 98, in main
top_values(tanks)
File "./wotalyzer.py", line 44, in top_values
print field + ": " + tank['full_name'] + "(" + tank[field] + ")"
TypeError: list indices must be integers, not str我怎样才能做到这一点？我想这样做，以便轻松添加新字段。
