如何使用python3将文本从一个文件追加到每行的开头，中间和结尾？

I am writing a script to change the formatting of the text from one file, and create a new text file with the changes in formatting. I have been able to remove unwanted characters, but haven't found a way to append text to the beginning of every line in the file.

我正在编写一个脚本来更改一个文件中文本的格式，并创建一个包含格式更改的新文本文件。我已经能够删除不需要的字符，但还没有找到一种方法将文本追加到文件中每一行的开头。

Content from the original file looks like:

原始文件中的内容如下所示：

DMA 123 USA 12345

What I need it to look like after appending data to the start, middle, and end of the string:

将数据附加到字符串的开头，中间和结尾后，我需要它看起来像什么：

<option label="DMA 123 USA" value="123"></option>

I have almost 100 lines that vary some, but follow the above formatting. I am trying to automate this as it will be a frequent task to adjust the original file to the new format for web publishing

我有近100行不同，但按照上面的格式。我正在尝试自动执行此操作，因为将原始文件调整为Web发布的新格式将是一项常见任务

I have been searching and haven't found any way to do it yet. Here is my current code:

我一直在寻找，但还没有找到任何办法。这是我目前的代码：

path = 'file.txt'
tvfile = open(path,'r')
days = tvfile.read()

new_path = 'tvs.txt'
new_days = open(new_path,'w')

replace_me = ['-' ,'(' ,')' ,',' , '"' , ]
for item in replace_me:
days = days.replace(item,'')
days = days.strip()

new_days.write(days)
print(days)

tvfile.close()
new_days.close()

Nit: you need to prepend, not append. That said, try something along these lines:

尼特：你需要前置，而不是附加。也就是说，尝试以下几点：

buffer = ""
for item in replace_me:
    line = "<option label=\""
    line = line + days.replace(item,'').strip()
    line = line + "\"></option>"
    buffer = buffer + line

new_days.write(buffer)
