Python interpreter?

Question

Python

https://www.youtube.com/watch?v=_aROt-HfLoE&list=P...
this video says that the interpreter takes the first line of code, reads the command, immediately converts the source code into binary and passes it to the processor

In another article, I read that the machine code for the interpreter is not needed.
Whom to trust?
Tell me how does this Python interpreter work? How does an interpreter make human-written code understandable to a computer?
