删除textfile-python中以“#|…”为边界的注释块

如何从文本文件中删除注释块，注释被封装在

和
中

infle:

#|\n this is some sort of foo bar\n that I don't care about|#\nthen there is a foo bar sentence that I want but i don't want that foo bar in within the hex pipe pipe hex comment block.#| and even so, i don't want this section to appear|#\n with some crazy sentence...

then there is a foo bar sentence that I want but i don't want that foo bar in within the hex pipe pipe hex comment block. with some crazy sentence...

所需输出：

#|\n this is some sort of foo bar\n that I don't care about|#\nthen there is a foo bar sentence that I want but i don't want that foo bar in within the hex pipe pipe hex comment block.#| and even so, i don't want this section to appear|#\n with some crazy sentence...

then there is a foo bar sentence that I want but i don't want that foo bar in within the hex pipe pipe hex comment block. with some crazy sentence...

除了以下内容之外，还有更好的方法删除注释块吗

txt = '''#|\n this is some sort of foo bar\n that I don't care about|#\nthen there is a foo bar sentence that I want but i don't want that foo bar in within the hex pipe pipe hex comment block.#| and even so, i don't want this section to appear|#\n with some crazy sentence...'''

pointer = 0
while pointer < len(txt):
    try:
        start = txt.index('#|',pointer)
        end = txt.index('|#\n',start)
        cleantxt+=txt[pointer:start]
        pointer = end+3
    except ValueError:
        cleantxt+=txt[pointer:]
        break

txt=''.#| \n这是一种我不关心的foo-bar\n然后我想要一个foo-bar句子，但我不希望这个foo-bar出现在hex-pipe-pipe-hex注释块中。#| |即使如此，我也不希望这个部分出现|#\n带有一些疯狂的句子…''
