How do you get double-underscores to display in markdown?

Question

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

__file__

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?

Answer 1

__file__

It works! Put backticks around the underscores.

Like this:

`__`file`__`

Answer 2

You can also put a backslash before the final underscore

__file_\_

gives you

__file__

Answer 3

You can use _ in place of left underscores. Example: __file__
