如何按用户分组并在python中显示他们的关注

Question

以下文本是来自原始数据文本文件的示例，用于执行分析。 原始数据的格式为：user1 跟随 user2 user3 user4。例如，第一行的意思是：tony 跟随 tom 和 frank。 因此，托尼是汤姆和弗兰克的追随者。

tony tom frank  (it means tony follows tom and frank)
tom             (it means tom follows no one)
tom tony jordan (it means tom follows tony and jordan)
frank tom tony  (it means frank follows tom and tony)
jordan frank    (it means jordan follows frank)
tom frank       (it means tom follows frank)


Thus
1. tom's followers are tony and frank
2. tony's followers are tom and frank
3. frank's followers are tony and jordan and tom
4. jordan's followers is just tom.

我想计算一个表格来分析谁的关注者最多。 我想得到这样的输出：user1有关注者：user2，user3，user4 我尝试的代码没有给我正确的代码。有人可以帮忙吗？

我试过如下：

**with open("sample.txt", 'r') as fhand:
    aCompleteUserDict = {}
    aCompleteUserList = []

    for line in fhand:
        allUsers = line.split()  # This part is to convert each line in the file into a list
        for aUser in allUsers[0:]:
            aCompleteUserDict[aUser] = allUsers[1:]  
            #fan = allUsers[0]

    print(aCompleteUserDict)**




***The actual output for my try is:***
{'tony': ['tom', 'tony'], 'tom': ['frank'], 'frank': ['frank'], 'jordan': ['frank']}


***My expected output format is:***

{'tony': ['tom', 'frank'], 'tom': ['frank', 'tony']], 'frank': ['tony', 'jordan', 'tom'], 'jordan': ['tom']}

这是一个可以轻松适应从文件读取的解决方案。

str_1 = 'tony tom frank'
str_2 = 'tom'        
str_3 = 'tom tony jordan'
str_4 = 'frank tom tony'
str_5 = 'jordan frank'
str_6 = 'tom frank'


str_list = [str_1, str_2, str_3, str_4, str_5, str_6]


aCompleteUserDict = {}

for string in str_list:
    allUsers = string.split()
    follower, followed = allUsers[0], allUsers[1:]
    for foll in followed:
        if foll not in aCompleteUserDict.keys():
            aCompleteUserDict[foll] = [follower]
        else:
            aCompleteUserDict[foll].append(follower)

print(aCompleteUserDict)

{'tom': ['tony', 'frank'], 'frank': ['tony', 'jordan', 'tom'], 'tony': ['tom', 'frank'], 'jordan': ['tom']}
