<p>Here are a few examples of how to use the <a class="reference internal" href="email.html#module-email" title="email: Package supporting the parsing, manipulating, and generating email messages, including MIME documents."><code class="xref py py-mod docutils literal"><span class="pre">email</span></code></a> package to read, write,
and send simple email messages, as well as more complex MIME messages.</p>
<p>First, let&#8217;s see how to create and send a simple text message:</p>
<div class="highlight-python3"><div class="highlight"><pre><span></span><span class="c1"># Import smtplib for the actual sending function</span>
<span class="kn">import</span> <span class="nn">smtplib</span>

<span class="c1"># Import the email modules we&#39;ll need</span>

<span class="c1"># Open a plain text file for reading.  For this example, assume that</span>
<span class="c1"># the text file contains only ASCII characters.</span>
<span class="k">with</span> <span class="nb">open</span><span class="p">(</span><span class="n">textfile</span><span class="p">)</span> <span class="k">as</span> <span class="n">fp</span><span class="p">:</span>
    <span class="c1"># Create a text/plain message</span>
    <span class="n">msg</span> <span class="o">=</span> <span class="n">MIMEText</span><span class="p">(</span><span class="n">fp</span><span class="o">.</span><span class="n">read</span><span class="p">())</span>

<span class="c1"># me == the sender&#39;s email address</span>
<span class="c1"># you == the recipient&#39;s email address</span>
<span class="n">msg</span><span class="p">[</span><span class="s1">&#39;Subject&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;The contents of </span><span class="si">%s</span><span class="s1">&#39;</span> <span class="o">%</span> <span class="n">textfile</span>
<span class="n">msg</span><span class="p">[</span><span class="s1">&#39;From&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="n">me</span>
<span class="n">msg</span><span class="p">[</span><span class="s1">&#39;To&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="n">you</span>

<span class="c1"># Send the message via our own SMTP server.</span>

<span class="n">s</span><span class="o">.</span><span class="n">quit</span><span class="p">()</span>
</pre></div>
</div>
<p>And parsing RFC822 headers can easily be done by the parse(filename) or
parsestr(message_as_string) methods of the Parser() class:</p>
<div class="highlight-python3"><div class="highlight"><pre><span></span><span class="c1"># Import the email modules we&#39;ll need</span>
<span class="kn">from</span> <span class="nn">email.parser</span> <span class="k">import</span> <span class="n">Parser</span>

<span class="c1"># If the e-mail headers are in a file, uncomment these two lines:</span>
<span class="c1"># with open(messagefile) as fp:</span>
<span class="c1">#     headers = Parser().parse(fp)</span>

<span class="c1">#  Or for parsing headers in a string, use:</span>
<span class="n">headers</span> <span class="o">=</span> <span class="n">Parser</span><span class="p">()</span><span class="o">.</span><span class="n">parsestr</span><span class="p">(</span><span class="s1">&#39;From: &lt;user@example.com&gt;</span><span class="se">\n</span><span class="s1">&#39;</span>
        <span class="s1">&#39;To: &lt;someone_else@example.com&gt;</span><span class="se">\n</span><span class="s1">&#39;</span>
        <span class="s1">&#39;Subject: Test message</span><span class="se">\n</span><span class="s1">&#39;</span>
        <span class="s1">&#39;</span><span class="se">\n</span><span class="s1">&#39;</span>
        <span class="s1">&#39;Body would go here</span><span class="se">\n</span><span class="s1">&#39;</span><span class="p">)</span>

<span class="c1">#  Now the header items can be accessed as a dictionary:</span>
<span class="nb">print</span><span class="p">(</span><span class="s1">&#39;To: </span><span class="si">%s</span><span class="s1">&#39;</span> <span class="o">%</span> <span class="n">headers</span><span class="p">[</span><span class="s1">&#39;to&#39;</span><span class="p">])</span>
<span class="nb">print</span><span class="p">(</span><span class="s1">&#39;From: </span><span class="si">%s</span><span class="s1">&#39;</span> <span class="o">%</span> <span class="n">headers</span><span class="p">[</span><span class="s1">&#39;from&#39;</span><span class="p">])</span>
