Node JS or Python for the backend?

Question

Python

Hello.
Self-taught programmer, 21 years old. Experience, starting from the first day of training - a little less than a year.
I just completed an internship and ended up in a junior position in an outsourcing company as a web developer.
One direction cannot be followed. Some tasks for layout, others for backing.
Main technology stack: HTML, CSS, JS/NodeJS/AngularJS, Elasticsearch.

There is no goal of becoming a jack-of-all-trades or an under-full stack. Therefore, he chose one direction - bek.

And at this stage, I was faced with a choice, which I ask you to help me decide:
Focusing on the demand, potential and better adaptability to the back,
What would you personally call the preferred technology - Python or NodeJS? And why?

Remark:
To be more specific, here are my main interests at work:
• Working with the web. The backend part is very interesting. I would like the front to be as small as possible.
• Interesting work with bots for various platforms.
• Very interested in working with the Internet, networks, data transmitted using protocols, etc.
• Interesting servers and linux.
• The sphere of information security is interesting.

Answer 1

node is not a language at all. but even if you omit this moment, that on zhs, that on a snake you can either cut good loot, or suck. the choice is yours.
demand is your skills and the ability to sell them, not your language.

Answer 2

Python because it's not just for web development. At the same time, it is worth starting to be interested in cloud infrastructures with how they can be used: a platform for web applications, DBMS, etc.

Answer 3

Symfony/rest api
One ORM is worth something.
Think about others.
And a node for the front, some kind of react or vue
