<p><strong>Source code:</strong> <a class="reference external" href="https://github.com/python/cpython/tree/3.7/Lib/email/mime/">Lib/email/mime/</a></p>
<hr class="docutils" />
<p>This module is part of the legacy (<code class="docutils literal notranslate"><span class="pre">Compat32</span></code>) email API. Its functionality
is partially replaced by the <a class="reference internal" href="email.contentmanager.html#module-email.contentmanager" title="email.contentmanager: Storing and Retrieving Content from MIME Parts"><code class="xref py py-mod docutils literal notranslate"><span class="pre">contentmanager</span></code></a> in the new API, but
in certain applications these classes may still be useful, even in non-legacy
code.</p>
<p>Ordinarily, you get a message object structure by passing a file or some text to
a parser, which parses the text and returns the root message object. However
you can also build a complete message structure from scratch, or even individual
<a class="reference internal" href="email.compat32-message.html#email.message.Message" title="email.message.Message"><code class="xref py py-class docutils literal notranslate"><span class="pre">Message</span></code></a> objects by hand. In fact, you can also take an
existing structure and add new <a class="reference internal" href="email.compat32-message.html#email.message.Message" title="email.message.Message"><code class="xref py py-class docutils literal notranslate"><span class="pre">Message</span></code></a> objects, move them
around, etc. This makes a very convenient interface for slicing-and-dicing MIME
messages.</p>
<p>You can create a new object structure by creating <a class="reference internal" href="email.compat32-message.html#email.message.Message" title="email.message.Message"><code class="xref py py-class docutils literal notranslate"><span class="pre">Message</span></code></a>
instances, adding attachments and all the appropriate headers manually. For MIME
messages though, the <a class="reference internal" href="email.html#module-email" title="email: Package supporting the parsing, manipulating, and generating email messages."><code class="xref py py-mod docutils literal notranslate"><span class="pre">email</span></code></a> package provides some convenient subclasses to
make things easier.</p>
<p>Here are the classes:</p>

is provided primarily as a convenient base class for more specific
MIME-aware subclasses.</p>
<p><em>_maintype</em> is the <em class="mailheader">Content-Type</em> major type (e.g. <em class="mimetype">text</em>
or <em class="mimetype">image</em>), and <em>_subtype</em> is the <em class="mailheader">Content-Type</em> minor
type (e.g. <em class="mimetype">plain</em> or <em class="mimetype">gif</em>). <em>_params</em> is a parameter
key/value dictionary and is passed directly to <a class="reference internal" href="email.compat32-message.html#email.message.Message.add_header" title="email.message.Message.add_header"><code class="xref py py-meth docutils literal notranslate"><span class="pre">Message.add_header</span></code></a>.</p>

(based on <em>_maintype</em>, <em>_subtype</em>, and <em>_params</em>), and a

<dd><p>Module: <code class="xref py py-mod docutils literal notranslate"><span class="pre">email.mime.text</span></code></p>
<p>A subclass of <a class="reference internal" href="#email.mime.nonmultipart.MIMENonMultipart" title="email.mime.nonmultipart.MIMENonMultipart"><code class="xref py py-class docutils literal notranslate"><span class="pre">MIMENonMultipart</span></code></a>, the
<a class="reference internal" href="#email.mime.text.MIMEText" title="email.mime.text.MIMEText"><code class="xref py py-class docutils literal notranslate"><span class="pre">MIMEText</span></code></a> class is used to create MIME objects of major type
<em class="mimetype">text</em>. <em>_text</em> is the string for the payload. <em>_subtype</em> is the
minor type and defaults to <em class="mimetype">plain</em>. <em>_charset</em> is the character
set of the text and is passed as an argument to the
<a class="reference internal" href="#email.mime.nonmultipart.MIMENonMultipart" title="email.mime.nonmultipart.MIMENonMultipart"><code class="xref py py-class docutils literal notranslate"><span class="pre">MIMENonMultipart</span></code></a> constructor; it defaults
to <code class="docutils literal notranslate"><span class="pre">us-ascii</span></code> if the string contains only <code class="docutils literal notranslate"><span class="pre">ascii</span></code> code points, and
<code class="docutils literal notranslate"><span class="pre">utf-8</span></code> otherwise. The <em>_charset</em> parameter accepts either a string or a
<a class="reference internal" href="email.charset.html#email.charset.Charset" title="email.charset.Charset"><code class="xref py py-class docutils literal notranslate"><span class="pre">Charset</span></code></a> instance.</p>
<p>Unless the <em>_charset</em> argument is explicitly set to <code class="docutils literal notranslate"><span class="pre">None</span></code>, the
MIMEText object created will have both a <em class="mailheader">Content-Type</em> header
with a <code class="docutils literal notranslate"><span class="pre">charset</span></code> parameter, and a <em class="mailheader">Content-Transfer-Encoding</em>
header. This means that a subsequent <code class="docutils literal notranslate"><span class="pre">set_payload</span></code> call will not result
in an encoded payload, even if a charset is passed in the <code class="docutils literal notranslate"><span class="pre">set_payload</span></code>
command. You can “reset” this behavior by deleting the
<code class="docutils literal notranslate"><span class="pre">Content-Transfer-Encoding</span></code> header, after which a <code class="docutils literal notranslate"><span class="pre">set_payload</span></code> call
will automatically encode the new payload (and add a new
<em class="mailheader">Content-Transfer-Encoding</em> header).</p>
<p>Optional <em>policy</em> argument defaults to <a class="reference internal" href="email.policy.html#email.policy.Compat32" title="email.policy.Compat32"><code class="xref py py-class docutils literal notranslate"><span class="pre">compat32</span></code></a>.</p>
