如何从文件创建字典？

Question

我正在尝试编写一个Python代码，该代码将允许我输入文本并逐行读取。在每一行中，单词只是作为关键字进入字典，数字应作为分配的值（如列表）。文件“ topics.txt”将由数百行格式相同的行组成：

1~cocoa

2~

3~

4~

5~grain~wheat~corn~barley~oat~sorghum

6~veg-oil~linseed~lin-oil~soy-oil~sun-oil~soybean~oilseed~corn~sunseed~grain~sorghum~wheat

7~

8~

9~earn

10~acq

等等，等等。我需要为ex的每个单词创建词典：理想情况下，名称“ grain”将是字典中的键，而值将是dict [grain]：[5,6，..]。类似地，“可可”将是另一个键，值将是dict [cocoa]：[1，..]不多，但到目前为止。

with open("topics.txt", "r") as fi:  # Data read from a text file is a string

    d = {}

    for i in fi.readlines():

        temp = i.split()

        #i am lost here

        num = temp[0]

        d[name] = [map(int, num)]

with open("topics.txt", "r") as file:  # Data read from a text file is a string    dict = {}    for fullLine in file:        splitLine = fullLine.split("~")        num = splitLine[0]        for name in splitLine[1:]:            if name in dict:                dict[name] = dict[name] + (num,)            else                dict[name] = (num,)
