(Python) 帮助修改剪贴板中的字符串

Question

基本上，我将 https://en.wikipedia.org/wiki/List_of_lists_of_lists 中的一堆列表复制到我的剪贴板中。当我运行我的程序时，它会在每一行前后添加项目符号。

例如：

Lists of Iranian films

将转换为：

•• Lists of Iranian films ••

等等。当我在该行之前添加项目符号时，该程序有效，但当我将它们放在它之后时，它只打印一个没有任何换行符的长字符串。谁能告诉我我做错了什么？

代码如下：

#bulletPointAdder.py   - Adds Wikipedia bullet points to the start and end
#of each line of text on the clipboard

import pyperclip
text=pyperclip.paste()      #paste a big string of text from clipboard into the 'text' string


# Separate lines and add stars
lines = text.split('\n')     #'lines' contains a list of all the individual lines up until '\n'
                             #lines= ['list of iserael films', 'list of italian films' ...]

for i in range(len(lines)):         #loop through all indexes in the "lines" list
    lines[i] = '••' + lines[i] + '••'   #add bullets before and after each line

text = '\n'.join(lines)         #put a '\n' in  between the list members (joins them) into a single string
pyperclip.copy(text)

在我的剪贴板中：

List of Israeli films before 1960
List of Israeli films of the 1960s
List of Israeli films of the 1970s
List of Israeli films of the 1980s

在记事本中粘贴的剪贴板：

••List of Israeli films before 1960••••List of Israeli films of the 1960s••••List of Israeli films of the 1970s••••List of Israeli films of the 1980s••

对您的代码做一点小改动（使用 os.linesep 而不是 '\n'）：

import os
import pyperclip
text=pyperclip.paste()     
                             #paste will paste a big string of text in 'text' string

# Separate lines and add stars
lines = text.split(os.linesep)     #lines contains a list of all the individual lines up cut before newline
                             #lines= ['list of iserael films', 'list of italian films' ...]

for i in range(len(lines)):         #loop through all indexes in the "lines" list
    lines[i] = '••' + lines[i] + '••'   #add bullets before and after each line

text = os.linesep.join(lines)         #put a newline in  between the list members (joins them) into a single string
pyperclip.copy(text)

通常，"new line" 指的是通常被解释为表示换行的任何字符集，其中包括：

CR LF DOS/Windows
旧款 Mac 上的 CR
Unix 变体（包括现代 Mac）上的 LF

CR是Carriage Return ASCII字符（Code 0x0D），通常表示为\r。 LF 是换行字符（代码 0x0A），通常表示为 \n.

我只是想让你写一个与平台无关的解决方案。因此 os.linesep
