无法比较包含字符串的2个Python集

我已经创建了2个python集，它们是由2个不同的CSV文件创建的，其中包含一些Sting

我正在尝试匹配这两个集合，以便它将返回2的交集（两个集合中的公共字符串都应返回）

这就是我的代码的外观：

from nltk.corpus import stopwords
from nltk.tokenize import word_tokenize
import string
import nltk
#using content mmanager to open and read file
#converted the text file into csv file at the source using Notepad++
with open(r'skills.csv', 'r', encoding="utf-8-sig") as f:
    myskills = f.readlines()
    #converting mall the string in the list to lowercase
    list_of_myskills = map(lambda x: x.lower(), myskills)
    set_of_myskills = set(list_of_myskills)
    #print(type(nodup_filtered_content))
print(set_of_myskills)
#open and read by line from the text file
with open(r'list_of_skills.csv', 'r') as f2:
    #using readlines() instead of read(), becasue it reads line by line (each 
    line as a string obj in the python list)
    contents_f2 = f2.readlines()
    #converting mall the string in the list to lowercase
    list_of_skills = map(lambda x: x.lower(), contents_f2)
    #converting into sets
    set_of_skills = set(list_of_skills)
print(set_of_skills)

这就是我正在使用的函数：

def set_compare(set1,set2):
if(set1 & set2):
    return print('The matching skills are: '(set1 & set2))
else:
    print("No matching skills")

运行代码后：

    set_compare(set_of_skills,set_of_myskills)

输出：

No matching skills

“skills.csv”的内容包括：

虽然我可以看到匹配的关键字，但我不明白为什么我得不到输出

也没有得到任何错误

比较两组字符串不会比较这些字符串的子字符串。您的程序实际上所做的是

foo = {'ABC', 'DEF', 'GHI'}
bar = {'AB', 'CD', 'DE', 'FG', 'HI'}

foo.intersection(bar) # returns {}

仅仅因为不同集合中的字符串之间存在共享字符，并不意味着集合具有交集。字符串

'ABC'

在第一个而不是第二个，字符串

'AB'

在第二个而不是第一个，以此类推

现在有点不清楚你到底想比较两个csv的交集是什么。是否要查找两者中的单个单元格？它们也必须在列中匹配吗？如果您提供有关预期输出的更多信息，那么我可以编辑此答案以提供更多信息

[编辑] 根据您的评论，看起来您想要的是分割逗号上的巨大字符串，使集合中的元素成为单个单元格。目前，这些集合只有一个元素，每个元素都只是一根巨大的弦，里面有很多技巧。如果你更换

list_of_myskills = map(lambda x: x.lower(), myskills)

与

---

并相应地替换另一个类似的行，那么您可能会更接近您所期望的内容。

这样做：更改.csv文件以包含技能单词，并用“，”分隔。每个文件一行

import pandas as pd
myskills = pd.read_csv("skills.csv",header=None)
set_of_my_skills = set(myskills.iloc[0,])
list_of_skills = pd.read_csv("list_of_skills.csv",header=None)
set_of_skills = set(list_of_skills.iloc[0,])
print(set_of_my_skills & set_of_skills)

基本上，我希望能够匹配来自CSVI和CSVI的整个字符串。我同意您提到的关于“ABC”和“AB”的内容。我知道两个文件中都有字符串，因为我在源文件中做了相应的更改，故意在运行代码时检查它们是否匹配。回答您的问题：我正在尝试匹配单个单元格。上面的编辑有意义吗？听起来像您想要的吗？它向我抛出了一个错误----------------------------------------------------------------------AttributeError Traceback（最后一次调用）in（）6 myskills=f.readlines（）7#将列表中的字符串转换为小写-->8 list of myskills=[x.strip（）.lower（），用于myskills.split（'，'）]9 set of myskills=set（list of myskills）10#print（type（nodup\u filtered\u content））AttributeError:“list”对象没有属性“split”，用此行替换代码“list_of_myskills=[y.strip（）.lower（）代表x中的x，在x.split（'，'）]中代表y的myskills]”非常有效。谢谢。
