Answer 2

ch Murali ,

python.org has the definitive information on every Python language feature, but its self-search is usually useless and returns 0 results for __repr__.

Instead, use a site search from an external search engine. I just pasted the following into DuckDuckGo and got a bunch of links directly to specific pages on python.org.

site:python.org __repr__

Another option, and the one I use most often is to go to the general index page on python.org and alphabetically drill down to the thing you're after. Everything's there, including __repr__.
