与平台无关的断行符:Linux、Windows和iOS

import os
keyword = 'physical'+ os.linesep + 'distancing'
print(keyword)

输出:

physical
distancing

您可以单独写入新行，也可以在单个字符串中写入，这样更容易。

示例1

输入

line1 = "hello how are you"
line2 = "I am testing the new line escape sequence"
line3 = "this seems to work"

你可以把“\n”分开写:

file.write(line1)
file.write("\n")
file.write(line2)
file.write("\n")
file.write(line3)
file.write("\n")

输出

hello how are you
I am testing the new line escape sequence
this seems to work

示例2

输入

正如其他人在之前的回答中指出的那样，将\n放在字符串中的相关点:

line = "hello how are you\nI am testing the new line escape sequence\nthis seems to work"

file.write(line)

输出

hello how are you
I am testing the new line escape sequence
this seems to work

Use:

"{}\n{}\n{}".format(
    "line1",
    "line2",
    "line3"
)

我个人更喜欢这种形式。

在Python中，你可以只使用换行符，即\n

\n -简单换行符插入工作:

# Here's the test example - string with newline char:
In [36]: test_line = "Hi!!!\n testing first line.. \n testing second line.. \n and third line....."

输出:

In [37]: print(test_line)

Hi!!!
 testing first line..
 testing second line..
 and third line.....

Java字符串文字中的大多数转义字符在Python中也有效，例如“\r”和“\n”。
