Python - 加入换行符 [英] Python - Join with newline

问题描述

在 Python 控制台中，当我输入:

<预><代码>>>>"\n".join(['I', 'would', 'expect', 'multiple', 'lines'])

给出:

'我\n会\n期望\n多行\n行'

虽然我希望看到这样的输出:

我将预计多线

我在这里遗漏了什么?

解决方案

控制台正在打印表示，而不是字符串本身.

如果你以print为前缀，你会得到你所期望的.

请参阅这个问题，了解有关字符串之间差异的详细信息和字符串的表示.超级简化，表示就是您在源代码中键入的内容以获取该字符串.

In the Python console, when I type:

>>> "\n".join(['I', 'would', 'expect', 'multiple', 'lines'])

Gives:

'I\nwould\nexpect\nmultiple\nlines'

Though I'd expect to see such an output:

I
would
expect
multiple
lines

What am I missing here?

解决方案

The console is printing the representation, not the string itself.

If you prefix with print, you'll get what you expect.

See this question for details about the difference between a string and the string's representation. Super-simplified, the representation is what you'd type in source code to get that string.
