<p><strong>Source code:</strong> <a class="reference external" href="https://github.com/python/cpython/tree/3.7/Lib/email/iterators.py">Lib/email/iterators.py</a></p>
<hr class="docutils" />
<p>Iterating over a message object tree is fairly easy with the
<a class="reference internal" href="email.compat32-message.html#email.message.Message.walk" title="email.message.Message.walk"><code class="xref py py-meth docutils literal notranslate"><span class="pre">Message.walk</span></code></a> method. The
<a class="reference internal" href="#module-email.iterators" title="email.iterators: Iterate over a message object tree."><code class="xref py py-mod docutils literal notranslate"><span class="pre">email.iterators</span></code></a> module provides some useful higher level iterations over
message object trees.</p>
<dl class="function">
<dt id="email.iterators.body_line_iterator">
<code class="descclassname">email.iterators.</code><code class="descname">body_line_iterator</code><span class="sig-paren">(</span><em>msg</em>, <em>decode=False</em><span class="sig-paren">)</span><a class="headerlink" href="#email.iterators.body_line_iterator" title="本定義的永久連結">¶</a></dt>
<dd><p>This iterates over all the payloads in all the subparts of <em>msg</em>, returning the
string payloads line-by-line. It skips over all the subpart headers, and it
skips over any subpart with a payload that isn’t a Python string. This is
somewhat equivalent to reading the flat text representation of the message from
a file using <a class="reference internal" href="io.html#io.TextIOBase.readline" title="io.TextIOBase.readline"><code class="xref py py-meth docutils literal notranslate"><span class="pre">readline()</span></code></a>, skipping over all the
intervening headers.</p>
<p>Optional <em>decode</em> is passed through to <a class="reference internal" href="email.compat32-message.html#email.message.Message.get_payload" title="email.message.Message.get_payload"><code class="xref py py-meth docutils literal notranslate"><span class="pre">Message.get_payload</span></code></a>.</p>

<dd><p>This iterates over all the subparts of <em>msg</em>, returning only those subparts that
match the MIME type specified by <em>maintype</em> and <em>subtype</em>.</p>
<p>Note that <em>subtype</em> is optional; if omitted, then subpart MIME type matching is
done only with the main type. <em>maintype</em> is optional too; it defaults to
<em class="mimetype">text</em>.</p>
<p>Thus, by default <a class="reference internal" href="#email.iterators.typed_subpart_iterator" title="email.iterators.typed_subpart_iterator"><code class="xref py py-func docutils literal notranslate"><span class="pre">typed_subpart_iterator()</span></code></a> returns each subpart that has a
MIME type of <em class="mimetype">text/*</em>.</p>
</dd></dl>
<p>The following function has been added as a useful debugging tool. It should
<em>not</em> be considered part of the supported public interface for the package.</p>
<dl class="function">

<span class="gp">>>> </span><span class="n">_structure</span><span class="p">(</span><span class="n">msg</span><span class="p">)</span>

</pre></div>
</div>
<p>Optional <em>fp</em> is a file-like object to print the output to. It must be
suitable for Python’s <a class="reference internal" href="functions.html#print" title="print"><code class="xref py py-func docutils literal notranslate"><span class="pre">print()</span></code></a> function. <em>level</em> is used internally.
<em>include_default</em>, if true, prints the default type as well.</p>
