Python: AttributeError: '_io.TextIOWrapper' object has no attribute 'split'
提问by Kaizer von Maanen
I have a textfile, let's call it goodlines.txtand I want to load it and make a list that contains each line in the text file.
我有一个文本文件，让我们调用它goodlines.txt，我想加载它并制作一个包含文本文件中每一行的列表。
I tried using the split()procedure like this:
我尝试使用这样的split()程序：
>>> f = open('goodlines.txt')
>>> mylist = f.splitlines()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: '_io.TextIOWrapper' object has no attribute 'splitlines'
>>> mylist = f.split()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: '_io.TextIOWrapper' object has no attribute 'split'
Why do I get these errors? Is that not how I use split()? ( I am using python 3.3.2)
为什么我会收到这些错误？我不是这样用的split()吗？（我正在使用python 3.3.2）

You are using strmethods on an open file object.
您正在str对打开的文件对象使用方法。
You can read the file as a list of lines by simply calling list()on the file object:
您可以通过简单地调用list()文件对象来将文件作为行列表读取：
with open('goodlines.txt') as f:
mylist = list(f)
This doesinclude the newline characters. You can strip those in a list comprehension:
这确实包括换行符。您可以在列表理解中去掉那些：
with open('goodlines.txt') as f:
mylist = [line.rstrip('\n') for line in f]
回答by Sheng
Try this:
尝试这个：
>>> f = open('goodlines.txt')
>>> mylist = f.readlines()
open()function returns a file object. And for file object, there is no method like splitlines()or split(). You could use dir(f)to see all the methods of file object.
open()函数返回一个文件对象。而对于文件对象，没有像splitlines()or那样的方法split()。您可以使用dir(f)查看文件对象的所有方法。

You're not reading the file content:
您没有阅读文件内容：
my_file_contents = f.read()
See the docsfor further infos
有关更多信息，请参阅文档
You could, without calling read()or readlines()loop over your file object:
您可以不调用read()或readlines()循环遍历您的文件对象：
f = open('goodlines.txt')
for line in f:
print(line)
If you want a list out of it (without \nas you asked)
如果你想要一个列表（没有\n你问的）
my_list = [line.rstrip('\n') for line in f]
