新的行字符是\n。它用于字符串内部。

例子:

    print('First line \n Second line') 

其中\n是换行符。

这将产生如下结果:

First line
 Second line

如果使用Python 2，则不对打印函数使用圆括号。

这里有一个更易读的解决方案，即使你不在顶级缩进(例如，在函数定义中)，它也能正确工作。

import textwrap
file.write(textwrap.dedent("""
    Life's but a walking shadow, a poor player
    That struts and frets his hour upon the stage
    And then is heard no more: it is a tale
    Told by an idiot, full of sound and fury,
    Signifying nothing.
"""))

正如在其他回答中提到的:“新的行字符是\n。它在字符串中使用”。

我发现最简单易读的方法是使用“format”函数，使用nl作为新行名称，并将你想打印的字符串转换为你要打印的确切格式:

Python 2:

print("line1{nl}"
      "line2{nl}"
      "line3".format(nl="\n"))

Python 3:

nl = "\n"
print(f"line1{nl}"
      f"line2{nl}"
      f"line3")

这将输出:

line1
line2
line3

通过这种方式，它可以执行任务，并且还提供了代码的高可读性:)

\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.....

Use:

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

我个人更喜欢这种形式。

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
