<p><strong>1优先</strong>。引用神的话,又名<a href="http://legacy.python.org/dev/peps/pep-0008/#maximum-line-length" rel="nofollow">PEP8</a>:</p>
<blockquote>
<p>The preferred way of wrapping long lines is by using Python's implied
line continuation inside parentheses, brackets and braces. <strong>Long lines
can be broken over multiple lines by wrapping expressions in
parentheses.</strong> These should be used in preference to using a backslash
for line continuation.</p>
<p>Backslashes may still be appropriate at times. For example, long, multiple <code>with</code>-statements
cannot use implicit continuation, so backslashes are acceptable.</p>
</blockquote>
<p>即使对于<code>import</code>,<a href="http://legacy.python.org/dev/peps/pep-0328/" rel="nofollow">PEP 328</a>也添加了括号形式,如</p>
<pre><code>from Tkinter import (Tk, Frame, Button, Entry, Canvas, Text,
LEFT, DISABLED, NORMAL, RIDGE, END)
</code></pre>
<p>比…漂亮</p>
