使用print()时如何换行和缩进长行? [英] How to wrap and indent long lines when using print()?

问题描述

我正在使用Python从Web服务中收集数据.数据本身就是将呈现给用户的列表.我已经将它打印出来，就像这样:

I'm using Python to gather data from a Web service. The data itself is a list that will presented to users. I've managed it that it's printed out like:

( 1)  Example of strings
( 2)  Example 4
( 3)  Another Example
( 4)  Another Example 2

我正在对数字使用正则(2).但是，如果线条很长，打印效果会很像.断开宽度是终端的长度(rxvt，gnome-terminal):

I'm using rjust (2) for the numbers. However, if the lines are very long, the printing will be like. The breaking width is the length of terminal (rxvt, gnome-terminal):

( 1)  Example of a very very very very long string and
that doesn't look fine
( 2)    Example of indented long line that is very very
long, example line
( 3)  Another Example
( 4)  Another Example of a very very long string and 
whatever here is

但是我想要的是这样的打印输出:

But what I've want is a print out like:

( 1)  Example of a very very very very long string and
      that doesn't look fine
( 2)    Example of indented long line that is very very
        long, example line
( 3)  Another Example
( 4)  Another Example of a very very long string and 
      whatever here is

有什么想法如何在不手动拆分行的情况下打印上述行?

Is there any ideas how to print the lines like above without breaking up the lines manually?
