类型错误：不可散列类型：'list'（使用集合）[重复]

Question

我只想将两个文本中的单词放在一个集合中，以获取所有唯一的单词。当我运行此代码时，我得到一个 Type Error: unhashable type: 'list'

我可以做些什么不同的事情？

infile1 = open("random.txt", 'r')
infile2 = open("random_encr.txt", 'r')

data1 = infile1.read()
data2 = infile2.read()

#close files
infile1.close()
infile2.close()

# replace all dots with empty string
data1 = data1.replace('.', '')
data2 = data2.replace('.', '')

# split words in data (splitted by whitespace) and save in words
words1 = data1.split()
words2 = data2.split()

set1 = set([words1])
set2 = set([words2])

set1.update(set2)

print(set1)

Answer 1

问题是您传递给set 的参数中有错误：

set1 = set([words1]) 正在定义一个项目列表 - 包含单词列表。

• 例如：[["a", "b", "c"]] ...
• 我猜你只想要["a", "b", "c"]。

删除[] 并执行set1 = set(words1)

Answer 2

以下是生成任一文档中出现的所有单词列表的一种方法：

infile1 = open("1.txt", 'r')
infile2 = open("2.txt", 'r')

data1 = infile1.read()
data2 = infile2.read()

#close files
infile1.close()
infile2.close()

# replace all dots with empty string
data1 = data1.replace('.', '')
data2 = data2.replace('.', '')

# split words in data (splitted by whitespace) and save in words
words1 = data1.split()
words2 = data2.split()

#create combined list
combinedList = []

for word in words1:
    if word not in combinedList:
        combinedList.append(word)

for word in words2:
    if word not in combinedList:
        combinedList.append(word)

print(combinedList)
