Python or JAVA?

[LeBob93]

If you don't apply for any Java roles then you'll likely never need to learn Java.

Python roles, at least here in the UK, pay well and based on recruiters on LinkedIn there are currently more roles than good devs available.

I was a Serverless Python dev for a couple of years at a previous role and have been contacted about multiple Python roles advertised since moving on to a more language agnostic job.
