# 20.1. `html` — HyperText Markup Language support

Source code: Lib/html/__init__.py

This module defines utilities to manipulate HTML.

`html.``escape`(s, quote=True)

  Convert the characters `&`, `<` and `>` in string s to HTML-safe sequences. Use this if you need to display text that might contain such characters in HTML. If the optional flag quote is true, the characters (`"`) and (`'`) are also translated; this helps for inclusion in an HTML attribute value delimited by quotes, as in `<a href="...">`.

  3.2 版新加入.

`html.``unescape`(s)

  Convert all named and numeric character references (e.g. `&gt;`, `&#62;`, `&#x3e;`) in the string s to the corresponding Unicode characters. This function uses the rules defined by the HTML 5 standard for both valid and invalid character references, and the `list of HTML 5 named character references`.

  3.4 版新加入.

Submodules in the `html` package are:

- `html.parser` – HTML/XHTML parser with lenient parsing mode

- `html.entities` – HTML entity definitions
