<p>In python, there are some special variables and filenames that are surrounded by double-underscores.  For example, there is the</p>

<pre><code>__file__ 
</code></pre>

<p>variable.  I am only able to get them to show up correctly inside of a code block.  What do I need to enter to get double underscores in regular text without having them interpreted as an emphasis?</p>

__file__
Put a backslash before the first underscore.
Like this:
```
```
\__file__
```
```
