흔히 이렇게 알고 있다

Markup.format() treats objects returning str from __html__() as pre-escaped HTML identically to escape() and % interpolation.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• Markup.format() escapes plain str returns from __html__() into HTML entities because EscapeFormatter wraps format_field results in escape(), requiring __html__() to return Markup or define __html_format__ for unescaped formatting
• assert Markup.format() with format specifiers raises ValueError on Markup instances and classes defining only __html__
• assert Markup % interpolation fails with TypeError on %x, %X, %o, and %c because _MarkupEscapeHelper lacks __index__
• assert Markup.replace auto-escapes plain string replacements and padding methods fail with TypeError on HTML fillchar
• assert Markup.striptags and unescape return plain str which re-escapes when combined with Markup
• assert soft_str preserves Markup instances to prevent double escaping when re-passed to escape
