The Footnotes extension adds syntax for defining footnotes in Markdown documents.
This extension is included in the standard Markdown library.
Python-Markdown's Footnote syntax follows the generally accepted syntax of the Markdown community at large and almost exactly matches PHP Markdown Extra's implementation of footnotes. The only differences involve a few subtleties in the output.
Footnotes[^1] have a label[^@#$%] and the footnote's content. [^1]: This is a footnote content. [^@#$%]: A footnote on the label: "@#$%".
A footnote label must start with a caret
^ and may contain any inline text
(including spaces) between a set of square brackets
. Only the first
caret has any special meaning.
A footnote content must start with the label followed by a colon and at least one space. The label used to define the content must exactly match the label used in the body (including capitalization and white space). The content would then follow the label either on the same line or on the next line. The content may contain multiple lines, paragraphs, code blocks, blockquotes and most any other markdown syntax. The additional lines must be indented one level (four spaces or one tab).
When working with multiple blocks, it may be helpful to start the content on a separate line from the label which defines the content. This way the entire block is indented consistently and any errors are more easily discernible by the author.
[^1]: The first paragraph of the definition. Paragraph two of the definition. > A blockquote with > multiple lines. a code block A final paragraph.

The following options are provided to configure the output:
PLACE_MARKER: A text string used to mark the position where the footnotes are rendered. Defaults to
///Footnotes Go Here///.
If the place marker text is not found in the document, the footnote definitions are placed at the end of the resulting HTML document.
UNIQUE_IDS: Whether to avoid collisions across multiple calls to
reset(). Defaults to
BACKLINK_TEXT: The text string that links from the footnote definition back to the position in the document. Defaults to
