python - 在两个相同的字符串之间从 python 中的 txt 文件中读取一段文本

Question

    self.viewerData = []
    tempViewerData = []
    tempViewer = []
    started = False
    with open("tittardata.txt", "r") as fp:
        for i, line in enumerate(fp.readlines()):
            if line.startswith("=="):
                started = True
                continue
            if started and line.startswith("--"):
                started = False
            if started == True:
                tempViewerData.append(line.rstrip("\n"))

我正在尝试从下面的 txt 文件中读取 block ，这些 block 在两端用“---”分隔。在第一个 block 中，分隔由以“===”开头并以“--”结尾的不同符号处理。即将到来的 block 由相同的符号解析，这使得提取 block 更加困难。到目前为止，这是我的尝试，感谢所有帮助。

这是文本文件的摘录:

=================
19.37/2
19.52/2
21.07/1
21.22/1
21.37/1
-------
19.37/2
19.52/2
-------

Answer 1

blocks = []
block = []

for line in f:
    if line[:3] in ('===', '---'):
        # don't record empty blocks, avoids empty block at start
        if block:
            blocks.append(block)
            block = []
    else:
        block.append(line.rstrip('\n'))
# needed if last block is not bounded by separator
if block:
    blocks.append(block)
