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~cocoa2~3~4~5~grain~wheat~corn~barley~oat~sorghum6~veg-oil~linseed~lin-oil~soy-oil~sun-oil~soybean~oilseed~corn~sunseed~grain~sorghum~wheat7~8~9~earn10~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,)
