python3 syntax highlighting currently not working

What is the problem?

Code blocks that are marked with python3 are not highlighted.

How can I reproduce it?

Here is the markdown of a random Leetcode problem: https://gist.github.com/parkershamblin/bde8ad0db5f1e78a68dc11c98b59d06a After downloading it and opening it up in vscode try running the command: Markdown: Print current document to HTML

The resulting html page should look like the one shown above.

Additional details

If you edit the markdown and change “python3” to “python” in front of the code blocks you will get syntax highlighting and the resulting html page will look like this. This is my current solution. However, you can see that the syntax highlighting is not 100% accurate with this approach (i.e. type hinting not being supported).

This is handled by VSCode’s built-in Markdown extension (https://github.com/microsoft/vscode/blob/eed137ff2ef7d6b96aa9a7b41307b4c21cda4627/extensions/markdown-language-features/src/markdownEngine.ts#L326-L335) which uses highlight.js that doesn’t seem to support python3.
