从具有多个定界符的.txt 文件中读取

Question

如果你有这样的事情：

A-B(8),F(10),G(15)
B-A(8),D(20)
F-A(8),D(12),C(30)

在一个.txt文件格式：

Store-NearbyStore1(distance),NearbyStore2(Distance)

您将如何读取并将其转换为数组或类似相邻矩阵的东西？

Answer 1

这里没有什么秘密，你只需要去做。 正确的？

text = """\
A-B(8),F(10),G(15)
B-A(8),D(20)
F-A(8),D(12),C(30)"""

import re
from collections import defaultdict

mapping = defaultdict(dict)
for line in text.splitlines():
    a,b = line.strip().split('-')
    for dest,dist in re.findall('([^(]*)\((\d*)\)', b ):
        mapping[a][dest] = dist
print(mapping)

Output：

defaultdict(<class 'dict'>, {'A': {'B': '8', ',F': '10', ',G': '15'}, 'B': {'A': '8', ',D': '20'}, 'F': {'A': '8', ',D': '12', ',C': '30'}})

Answer 2

with open("path", "r") as f:
    output = dict()
    for line in f:
        name, content_str = line.split("-")
        inner_dict = dict()
        contents = content_str.split(",")
        for content in contents:
            inner_name, number = content.split("(")
            inner_dict[inner_name]=int(number[:-1])
        output[name]=inner_dict
