说我有一个类似的数组:
[[1356, a], [478, b], [60, c], [61, d]]
是否可以重新排序以匹配数组:
[d, b, a, c]
像:
[[61,d], [478,b], [1356,a], [60,c]]
我想要的订单位于csv文件的第二列。所以我有:
with open('data.csv', "r") as csvfile:
order = csv.reader(csvfile, delimiter = ',')
code_order=[]
for row in order:
code_order.append(row[2])
reordered_output=[]
for i,x in enumerate(code_order):
where x[i] in result
reordered_ouput[i] = result
print(reordered_output)
答案 0 :(得分:7)
其中一种方法是将sorted
与key
>>> a = [[1356, 'a'], [478, 'b'], [60, 'c'], [61, 'd']]
>>> b = ['d', 'b', 'a', 'c']
>>> sorted(a, key = lambda x : b.index(x[1]))
[[61, 'd'], [478, 'b'], [1356, 'a'], [60, 'c']]
