How does the django template engine work?

Question

Django

I can't figure out how Django's template engine works. I don’t know how it is possible to implement a function in python that did something with another document by a simple command, without any imports.

Answer 1

Approximately the same as any interpreter. Parses the source code, performs lexical analysis, generates tokens, creates an abstract syntax tree, executes it.

Answer 2

A template engine for displaying information, according to the idea, it should not change anything at all (there are nuances, but this is rather for those who understand exactly what they are doing)
