我有一个脚本,它接收一个txt文件,其中包含作为程序输入的属性列表。对于每个属性,如果满足脚本的条件,它将打印出属性名称。但是,每个属性可能会多次满足,输出会多次打印。我现在想这样做:
condition 1 satisfied by A,B,C,D
condition 2 satisfied by A,B
condition 3 satisfied by B,D
我该怎么做? 我当前的输出看起来像
A
A
condition 3 not satisfied by A
B
B
B
condition 1 not satisfied by C
condition 2 not satisfied by C
C
D
condition 2 not satisfied by D
D
答案 0 :(得分:0)
如何(在伪python代码中)
import collections
result = collections.defaultdict(list)
for attr in [A, B, C, D]:
for cond in [condition1, condition2, ...]:
if attr satisfies cond:
result[cond].append(attr)
print result
输出:
{cond1: [A, B], cond2: [A], cond3: [C,D], ...}
我不确定这是你想要的。您没有明确(足够)说出您的输入是什么以及您想要输出的内容。
