Let's focus on France:

1) there are ~800 000 person aged 15. (Source:
https://www.insee.fr/fr/statistiques/1892088?sommaire=1912926 )

2) 40% of these are pupils in the "filière générale" (Source:
https://fr.wikipedia.org/wiki/Baccalaur%C3%A9at_en_France#Statistiques ).

3) Since 2017, Python is the language used to teach algorithmics to these
pupils.

=> We can conclude that there are at least 320 000 pupils learning Python
this year, and safely assume that most of them are not "professional
programmers".

Note also that this number is accretive (i.e.: 320 000 this year, 640 000
next year, etc.).

4) The annual turnover for the IT sector in France (including: software
vendor, service and consulting) was 54 billions euros in 2017. This
probably translates to around or less than 600 000 IT professionals. How
many of them are developers ? I have no idea, but I'm sure it's less that
50%. How many of them are developing professionally in Python ? I have no
idea, I'd guess less than 10%, but let's assume 20%.

=> This gives less than 60 000 professional Python programmers in France.
Probably much less.

Conclusion: there are probably more than 5 times more non professional
Python programmers in France (counting only the high-school pupils, not
other categories such as their teachers, but also scientist, sysadmins or
hobbyist) than professional programmers.

Next year it will be (more than) 1 to 10. The year after that, 1 to 15, etc.
