Question

我在文件“ File1”中有一个文本，其中包含以下文本：

-Accounting  
-HR

Some text  

-IT  
--Networks   
--Storage  
--DBA

我需要一段代码来逐行读取File1，并用适当的HTML标记替换“-”和“-”，并将下面显示的最终结果保存在文本文件File2中。

<ul>
<li>Accounting</li>
<li>HR</li>
</ul>

Some text

<ul><li>IT
       <ul>
          <li>Networks</li>
          <li>Storage</li>
          <li>DBA</li>
         </ul>
         </li></ul>

到目前为止，我尝试了以下代码。

我将两个用于检查当前行是否最初包含“-”或“-”的布尔值设置为False。如果当前行中有“-”或“-”，则代码会在该行的开头添加适当的标记，将布尔值更改为True，然后转到下一行。

现在布尔值用于查看前一行中是否有“-”或“-”，如果有破折号，它将在行的开头添加适当的标记，该标记应在前一行中，但是我们已经在下一行中了。另一种方法是检查下一行是否以“-”或“-”开头，但我不确定该如何做。当我使用next（）时，该行被跳过。可以同时读取两个文件，其中一个文件位于前一行，然后检查下一行中的文件是否是更好的解决方案？

                    new_line = "</li><li>" + current_line[1:]

下面的代码满足了我的需要。

with open("finalfile.txt", 'w', encoding='utf-8') as File2, open("test.txt", "r", encoding='utf-8') as File1:
previous_line = ""
new_line = ""
double_dash_prev_line = False
single_dash_prev_line = False
for line in File1:
    current_line = line
    if line[0] == "-":
        if line[1] != "-":
            if single_dash_prev_line == False and double_dash_prev_line == False:
                new_line = "<ul><li> " + current_line[1:]
                File2.write(new_line)
                single_dash_prev_line = True
                double_dash_prev_line = False
            elif single_dash_prev_line == True:

        elif line[1] == "-":
