如何使用print()包装和缩进长行？

Question

我正在用Python从一个网络服务获取数据。这些数据是一个列表，最后会展示给用户。我已经让它打印出来像这样：

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

我使用了rjust(2)来处理数字。不过，如果行很长，打印出来的效果就会变成这样。换行的宽度是终端的长度（比如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

但我想要的打印效果是这样的：

( 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

有没有什么办法可以像上面那样打印，而不需要手动去换行呢？

使用 textwrap 模块：http://docs.python.org/library/textwrap.html

 textwrap.fill(text, initial_indent='', subsequent_indent='      ')
