<p>即使保证了编写所有代码的语法全部正确，也没法避免突发情况，比如让用户输入内容的时候，你能保证用户不会输入你无法处理的内容？比如你能保证运行的电脑不会突然出现硬件故障？比如你能保证需要网络的程序，网络不会突然断掉？突发情况是我们无法一一枚举的，这时候脚本直接终止并不是一个好主意。</p>

<p>当程序运行出现意外情况的时候，系统会自动生成一个Error对象来通知程序，如果我们没有做异常处理，那么程序就会像我们之前看到的那样直接罢工不干，如果我们编写了相关的异常处理代码，则会进行“错误处理”，以便让程序能够继续运行下去。</p>

<h3 id="使用tryexcept结构捕获并处理异常"><a name="使用tryexcept结构捕获并处理异常" class="anchor-navigation-ex-anchor" href="#使用tryexcept结构捕获并处理异常"><i class="fa fa-link" aria-hidden="true"></i></a>使用try...except结构捕获并处理异常</h3>
|
||
<p>异常处理的通用结构语法如下（这是日常我用得最多的一种结构，一般来说，刚开始仅掌握这种结构也基本上够用了）：</p>
|
||
<pre class="language-"><code class="lang-python"><span class="token keyword">try</span><span class="token punctuation">:</span>
|
||
<span class="token comment"># 业务执行代码，这里面可能会有让程序报错的代码，放到这里来</span>
|
||
<span class="token punctuation">.</span><span class="token punctuation">.</span><span class="token punctuation">.</span>
|
||
<span class="token keyword">except</span> Exception <span class="token keyword">as</span> e<span class="token punctuation">:</span>
|
||
<span class="token comment"># 如果在try块的代码中有报错的代码，则会执行except块的代码，否则不执行</span>
|
||
<span class="token punctuation">.</span><span class="token punctuation">.</span><span class="token punctuation">.</span>
|
||
</code></pre>
|
||
<p>是不是很像流程控制的赶脚？对的，就是需要注意缩进的。</p>
|
||
<p>我们可以将可能出现问题的代码放到try块中，如果报错则会执行except块中的代码。<code>Exception</code>是一个通用的异常类，基本上各种异常都基于此类来派生，所以写它一般就可以了，至于其他更高级的应用我们后面课程会讲。<code>as e</code>是把捕获的异常赋值给一个自定义的变量<code>e</code>，当然你也可以写其他的名字，约定俗成一般用这个。这个<code>e</code>我们称之为被赋值后的异常对象，通过这个异常对象我们可以获取相关的异常信息。在except块中，一般可以print这个值<code>e</code>用来查看具体的异常是什么。关于异常对象，后面的课程中将会有更详细的讲解。</p>
|
||
<p>我们来看一个小例子：</p>
|
||
<pre class="language-"><code class="lang-python"><span class="token comment"># coding:utf-8</span>
|
||
<span class="token keyword">try</span><span class="token punctuation">:</span>
|
||
<span class="token comment"># 除数不能为0，所以一定会报错</span>
|
||
a <span class="token operator">=</span> <span class="token number">1</span> <span class="token operator">/</span> <span class="token number">0</span>
|
||
<span class="token keyword">except</span> Exception <span class="token keyword">as</span> e<span class="token punctuation">:</span>
|
||
<span class="token keyword">print</span><span class="token punctuation">(</span>e<span class="token punctuation">)</span>
|
||
</code></pre>
|
||
<p>是不是很简单呢？</p>
|
||
<blockquote>
|
||
<p>[!danger]</p>
|
||
<p>有的同学会说，那么我们把所有的业务代码都放到try块中不就不会有任何问题了吗？我们需要小心的是，在try语句块中的代码不要有太多，因为过多的代码语句放到try块中，出现异常的可能性就会大大增加，后续分析异常原因的难度也会大大增加。而且有的时候可能要针对不同的异常类提供不同的处理逻辑（关于不同的异常类，我们在后面的课程中会讲到），这样编程的难度就会增加。</p>
|
||
<p>所以我们的原则是，写多个try...except块，把感觉可能出现异常的程序段落分别写到多个try块里，分别捕获不同的异常并针对性处理。对于基本不大可能出现问题的程序段落，就像我们往常一样正常写就好了，可以不放到异常处理段落里。</p>
