python之如何从文件在 Python 中创建字典，其中值是一个列表

我有一个 txt 文件，我想将值读入字典。与普通字典不同的是，每个key的值都是一个值对，例如:

tiger eat meat 
tiger eat people 
rabbit eat carrot 
people can walk 
trees has root 
people has hand 

我想要一本字典，

tiger, {eat, meat}, {eat, people} 
rabbit, {eat, carrot} 
trees, {has, root} 
people, {can, walk}, {has, hand} 

我是否应该只读取行，拆分(\n) 为3 个项目并将第一个存储为键，将其余两个存储为值？或者有更好的方法来存储这两个值？

我的目标是，当我查询老虎吃什么时，我想得到答案 meat 和 people。

请您参考如下方法:

import collections 
 
lines=[] 
with open('data1', 'r') as f: 
    lines=list(map(lambda line:line.strip(), f.readlines())) 
 
d, flag=collections.defaultdict(list), False 
for line in lines: 
    temp=list(map(lambda x:x.strip(), line.split())) 
    d[temp[0]].append(temp[1:]) 
print(d) 

这是输出:

$ cat data1 
tiger eat meat 
tiger eat people 
rabbit eat carrot 
people can walk 
trees has root 
people has hand 
$ python3 a.py  
defaultdict(<class 'list'>, {'rabbit': [['eat', 'carrot']], 'trees': [['has', 'root']], 'tiger': [['eat', 'meat'], ['eat', 'people']], 'people': [['can', 'walk'], ['has', 'hand']]}) 

如果你想要这个结构:

$ python3 a.py  
defaultdict(<class 'list'>, {'people': [{'can': 'walk'}, {'has': 'hand'}], 'tiger': [{'eat': 'meat'}, {'eat': 'people'}], 'trees': [{'has': 'root'}], 'rabbit': [{'eat': 'carrot'}]}) 

将脚本中的倒数第二行替换为:

d[temp[0]].append({temp[1]:temp[2]})
