输出到终端时如何使用适当的换行符显示 .txt 文件中的文本

Question

我正在编写一个相对基本的打字测试脚本，以便在终端中运行。我有一个示例文本块，保存为 text_block.txt:

Roads go ever ever on,
Over rock and under tree,
By caves where never sun has shone,
By streams that never find the sea;
Over snow by winter sown,
And through the merry flowers of June,
Over grass and over stone,
And under mountains in the moon.

以及以下用于读取此内容的函数：

def load_text():
    with open("text_block.txt", "r") as f:
        lines = []
        for line in f:
            lines.append(line.strip())
        lines = ''.join(lines)
        return lines

在终端中显示时给出以下内容：

Roads go ever ever on,Over rock and under tree,By caves where never sun has shone,By streams that never find the sea;Over snow by winter sown,And through the merry flowers of June,Over grass and over stone,And under mountains in the moon.

我如何让它有适当的换行符来模仿文本文件的格式？

Answer 1

您可以通过在所有单词之间插入换行符来获得所需的输出：

a = ["abc", "deg", "II"]
b = "\n".join(a)
>>> b
'abc\ndef\nII'
>>> print(b)
abc
deg
II

但是您可能想在末尾添加一个换行符，在这种情况下只需添加：

b += "\n"
>>> print(b)
abc
deg
II

但是您也可以改进您的代码。您可以使用列表理解来删除一些额外的行（它与您的示例相同）。

with open() as f:
    return "".join([for line in f])

删除 .strip() 将保留文件中的所有内容（包括现有的换行符）。

或更短：

with open() as f:
    return "".join(f.readlines())
