如何在python中使用split方法从文本文件中生成一袋单词

Question

我正在努力学习TFIDF。但是我不能从文件中找到这些字。

代码：

docA = open("/home/user/Desktop/da/doca","r")
print(docA.read())
bowA = docA.split(" ")

错误：

AttributeError                            
Traceback (most recent call last)
<ipython-input-32-06e07f9dd975> in <module>
----> 1 bowA = docA.split(" ")

AttributeError: '_io.TextIOWrapper' object has no attribute 'split'`
Can anyone help me solve this?

Answer 1

我假设你是这个意思：

docA = open("/home/user/Desktop/da/doca","r")
# print(docA.read())
bowA = docA.read().split(" ") # or just split() will do
docA.close()

当您调用read()时，读游标读取整个文件，将读游标留在最后。因此再次调用read()将返回空字符串。因此，如果您想要打印内容，可以将内容赋给一个变量，打印它并根据需要使用它：

docA = open("/home/user/Desktop/da/doca","r")
data = docA.read()
print(data)
bowA = data.split()
docA.close()

或者简单地说

with open("/home/user/Desktop/da/doca","r") as docA:
    data = docA.read()
print(data)
bowA = data.split()

Answer 2

您希望使用返回的字符串而不是文件句柄：

docA = open("/home/user/Desktop/da/doca","r")
document_string = docA.read()
bowA = document_string.split()

您可以只调用split，默认情况下它会拆分空格
