我正在撰寫一個相對基本的打字測驗腳本以在終端中運行。我有一個示例文本塊，它被保存為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.
以及以下函式來讀取它：
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
在終端中顯示時給出以下內容：
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.
我如何讓它有適當的換行符來模仿文本檔案的格式？
uj5u.com熱心網友回復：
您可以通過在所有單詞之間插入換行符來獲得所需的輸出：
a = ["abc", "deg", "II"]
b = "\n".join(a)
>>> b
'abc\ndef\nII'
>>> print(b)
abc
deg
II
但是，您可能希望在末尾添加換行符，在這種情況下，只需添加：
b = "\n"
>>> print(b)
abc
deg
II
但是您也可以改進您的代碼。您可以使用串列理解來洗掉一些額外的行（它與您的示例相同）。
with open() as f:
return "".join([for line in f])
洗掉.strip()將保留檔案中的所有內容（包括現有的換行符）。
或更短：
with open() as f:
return "".join(f.readlines())
