格式化从文件中捕获的随机行时出现问题

Question

此代码 returns 来自文件的随机 3 行。它们成套返回，我想以可展示的格式打印出来。你会怎么做？

这是代码。

import random

with open("/Users/will/Dropbox/zettelkasten/Super Slogans 202012281549.md") as file_in:
    lines = []
    for line in file_in:
        lines.append(line.replace(u'\xa0', u' '))
    sample = (f' {random.sample(lines, 3)}')
print(sample)

原始文件看起来像。

- Divided focus leads to divided results.
- Where I point my attention becomes how I spend my life.
- What is natural is not supernatural.
and 602 other lines.

这是我得到的输出。

 ['- Divided focus leads to divided results.\n', '- Where I point my attention becomes how I spend my life.\n', '- What is natural is not supernatural.\n']

这是所需的输出。

- Divided focus leads to divided results.
- Where I point my attention becomes how I spend my life.
- What is natural is not supernatural.

我试过没有成功

print(*sample, end="\n ")
print(*sample, sep="\n")
print('\n'.join(sample))

Answer 1

尝试：

f = open("/Users/will/Dropbox/zettelkasten/Super Slogans 202012281549.md", 'r') 
sample = f.read()
print(sample)

Answer 2

我怀疑你有一些奇怪的行尾。

这对我来说效果很好，并且使用了您尝试过的打印语句之一：

import random

with open("test.txt") as file_in:
    lines = []
    for line in file_in:
        lines.append(line[:-1])
    sample = random.sample(lines, 3)
print('\n'.join(sample))

test.txt中的内容：

- Divided focus leads to divided results.
- Where I point my attention becomes how I spend my life.
- What is natural is not supernatural.
- Divsasdided focus leads to divided results.
- Where I point my attadasdntion becomes how I spend my life.
- What is natural is dasdanot supernatural.
- Diviadsadded focus leaasadaads to divided results.
- Where I point myadasd attention becomes hasdaow I spend my life.
- What is naturaladasd is not supernatural.
- Dividedassassss focus leads to dividesssd results.
- Whersssse I point my attention becomes hosssssw I spend my life.
- Whdsdasfasfaat is natural is not dfgsdfsdfsdsupernatural.

在从 here 启动的 Jupyter 环境中使用该代码和文本文件内容进行尝试，以分离出您首先要进行的机器或特定文件。

append 语句中的切片删除了行尾。如果您涉及奇怪的行结尾，这可能对您有用。如果你有典型的行尾，你可以只使用 strip() 方法，即，为了附加使用 lines.append(line.strip()).
通过将行尾添加回最后 join，您可以避免处理可能合并的最后一行，因为它没有行尾而其他行有。
