在python中附加到文件后没有EOL [英] no EOL after append to file in python

问题描述

我尝试使用以下代码使用 python 附加到文件:

I try to append to file with python using this code:

with open("test.txt", "a") as myfile:
    myfile.write("appended text")

问题是当我用vim打开一个文件时，我在底部收到来自vim的消息:

The problem is that when I open a file with vim, I get a message from vim at the bottom:

"test.txt" [noeol] 2L, 27C

据我所知，这意味着该文件中没有 EOL.它发生在附加 python 之后.如果我用 cat 打印文件，我得到:

As I understand that means there is no EOL in that file. And it happens after appending with python. If I print the file with cat, I get:

user@myubuntu:~/py_code$ cat test.txt
appended text
appended textuser@myubuntu:~/py_code$

当我用 vim 编辑 test.txt 并保存时，之后我从 cat 得到结果:

When I edit test.txt with vim and save, afterwards I get results from cat:

user@myubuntu:~/py_code$ cat test.txt
appended text
appended text
user@myubuntu:~/py_code$

注意user@myubuntu:~/py_code$"现在应该在新行上.所以我得出结论，在附加 python 后 EOL 存在一些问题，但我不明白为什么以及如何解决这个问题.

Pay attention that "user@myubuntu:~/py_code$" now is on the new line as it should be. So I make conclusion there is some problem with EOL after appending with python, but I do not understand why and how to fix this.

推荐答案

在每一行追加换行符 (\n).

Append newline (\n) to each line.

myfile.write("appended text\n")

附注.EOL(行尾)是换行符.

PS. EOL (end-of-line) is newline.
