如何将长字符串写入文本文件？

Question

有没有办法在python3中将长字符串写入文本文件，以便字符串可以写入多行？这是我到目前为止所尝试的。

这是我想要做的事情

    from nltk.tokenize import word_tokenize

    my_list = word_tokenize(my_text) 
    my_list_string = ' '.join(my_list)

    outfile = open("my_comp.txt", "a") 
    outfile.write(my_list_string ) 
    outfile.close()

在Python中有一个名为textwrap的文库：

>>> import textwrap
>>> strs = "Is there a way to write a long string of words to a text file in python3 so that the string can be written over several lines? This is what I have tried so far. Is there a way to write a long string of words to a text file in python3 so that the string can be written over several lines? This is what I have tried so far. "

如下工作：

>>> print (textwrap.fill(strs, 20))
Is there a way to
write a long string
of words to a text
file in python3 so
that the string can
be written over
several lines? This
is what I have tried
so far. Is there a
way to write a long
string of words to a
text file in python3
so that the string
can be written over
several lines? This
is what I have tried
so far.

或更改行长度：

>>> print (textwrap.fill(strs, 40))
Is there a way to write a long string of
words to a text file in python3 so that
the string can be written over several
lines? This is what I have tried so far.

看到你的代码后，我不确定还有其他方法可以在每个第n个标记处插入一个新行

但谁知道n应该多大......

你应该把它留给打开文件的程序吗？
