This is what worked for few of my friends who were laid off last year (I am a assistant professor on local uni but I own dev agency and dev 9-5 as pythonista!)

  1. learn python 
  - https://books.trinket.io/pfe/ + https://python.swaroopch.com/ (in parallel)
  - https://effectivepython.com/ (skim, dive deeper once you have job)
  - https://www.programiz.com/python-programming (skim, look at examples, type out)

  2. apply python 
  - https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world
  - miguel tutorial is all you need to get hired. go through it meticulously, make sure you understand everything
  - https://www.fullstackpython.com/ (skim, just so you know the keywords)

  3. update your cv
  - this step is optional and shady, but will improve your odds
  - reuse all your current experience but replace php tech with python (switch keywords)
  - if your cv entries are <1.5y change the dates, recruiters prefer 2-3 years per entry.

  4. find job asap, contiue grinding once you have job.
  - if you understand miguel tutorial, you can learn everything else you need once you got the job
  - market yourself as python software engineer/ devops python, NOT junior, NOT senior

This works.

if you have more questions, shoot :)
