Question

我在阅读特定行时遇到问题。它类似于这里回答的问题： python - Read file from and to specific lines of text 不同的是，我没有固定的结束标记。让我举个例子：

--------------------------------
\n
***** SOMETHING *****     # i use this as my start
\n
--------------------------------
\n
data of interest
data of interest
data of interest
\n
----------------------- #this will either be dashes, or EOF
***** SOMETHING *****
-----------------------

我尝试过类似上面的链接，但我不能创建一个if语句来打破循环，因为我不知道它是不是EOF。

Answer 1

这个怎么样：

def getBlocks(filepath):
    with open(filepath) as f:
        blocks = []
        go = False
        for line in f:
            if line.strip() == startDelimiter:
                block = ''
                go = True
            if go:
                block += line
            if line.strip() == endDelimiter:
                blocks.append(block)
                block = ''
                go = False
        if block:
            blocks.append(block)
    return blocks

Answer 2

美丽的是，如果你点击EOF，文件将停止迭代。

ended = False
for line in f:
    ended = line == MY_END_MARKER

Answer 3

你能不能做到

parts = my_file.read().split("-----------------------")
print parts

Python读取特定的文本行
