以“&”作为分隔符读取多行文件

Question

I have a file which contains the following content:

This is the first line.
&
This is the second line
but without separator.
&
This is the third line.
...

Each line terminates with a \n . I want to convert this file input into the following list: ['This is the first line.', 'This is the second line but without separator.', 'This is the third line.', ...]

My actual code looks like:

file = open("/path/to/file", "r")
list = [line.rstrip() for line in file if not line.rstrip() is "&"]

The problem is that the multi line section gets separated in the list but I want it togehter with or without a \n in it.

I hope someone can give me a hint. Thanks!

Answer 1

How about read all the lines and join them as a single string, then use String.split("&")

with open("test.txt") as file:
    lines = file.read()

print(lines.split("&"))
# to remove the \n
print(lines.replace("\n", "").split("&"))

Answer 2

Here is a working example. You already know how to read the file, here is how you might parse the contents.

file_contents = """This is the first line.
&
This is the second line
but without separator.
&
This is the third line."""

all_lines = []
for l in file_contents.split('&'):
    all_lines.append(" ".join(l.split('\n')).rstrip())

print(all_lines)

Prints:

['This is the first line.', ' This is the second line but without separator.', ' This is the third line.']

Answer 3

just split the whole file by & and remove whitespace (assuming that they should just be separated by & )

l = [s.strip().replace('\n', ' ') for s in file.read().split('&')]
