Thanks a lot for your answers.
That's true. I had a project which used Qt4.7, and I have still on my laptop.
I have not so big knowledge about compiling and building stuff, so I have to 
get rid of 3.10 version.
OK, then I try to remove Python 3.10 and to install 3.9.6.
Best regards
Mohsen

Thanks!  I don't need that right now, but it's good to know which
decoding hoop I would have to jump through, if I did.

Cheers,

[OSys PL Labs] 3 UI/UX Research Engineer Positions for Progr. Languages and Tools (Remote)

[Nick Papoylias]

Dear colleagues,

The newly founded PL (Programming Languages) research Group at OutSystems

has a goal of exploring the UI/UX frontier of Programming Tools.

We are looking for 3 UI/UX Research Engineers for Programming Languages &
Tools (Remote) to join our group. Please forward to anyone you think might
be interested by our call:

Europe/EMEA:
https://www.outsystems.com/careers/job-detail/8a7887a87acffd16017b1cedb4930469/

US/Americas:
https://www.outsystems.com/careers/job-detail/8a7885a87b55f750017b7479ec9f365b/

India/APAC:
https://www.outsystems.com/careers/job-detail/8a7883a97ad004d8017b1011897d76de/

Best Regards,

Dr. Papoulias (@npapoylias )
*Director of Research **@OutSystems* 

==

*If you consider yourself (or aspire to be) a UI/UX expert with programming
experience that wants to: “Boldly go where no programmer has gone before”
don’t let any impostor syndrome stop you, apply to join us! What we are
looking for in our research group -- first and foremost -- is explorers.
Take a look at this short video to quickly learn more about
OutSystems: https://youtu.be/0gx3hMMDOZI. *



*Responsibilities:*


** Your base responsibility will be the development of research prototypes
from an engineering perspective. Nevertheless, the research nature of these
prototypes will almost always require you to either learn a new language, a
new system or way of working. You will always be given time and guidance
(bibliography, books and an engineering starting point) to do so. The
director of the group will always be there to guide you with all aspects of
your work.*


** Once this base responsibility is fulfilled your UI/UX experience and
expertise will help us go even further. What can we add to a good prototype
to bring aesthetics and usability to the mix ? What will make us smile
every time we use it ?*


** When you become comfortable with the above responsibilities you can
start proposing your own experiments to the team and guide our newest
members through the whole R&D process.*
** Finally, according to the group’s needs you will be tasked to present
our work to colleagues, internally or externally (to the wider industrial
and academic community), participate in conferences, publications and in
the general dissemination of our work.*

Would you also prefer `twothousandthreehundredandtwentythird(ls)` over
`ls[2322]`?

[Off-Topic?] I love Python

[Emir Geçir]

   I really love Python, it has an easy to understand and write syntax, it
   can get EVERY task done when used right and has a great community on
   platforms like Reddit, Discord etc.
   **
   All the work every contributor, especially Guido and Mark Hammond has put
   into this language over years that is even longer than my lifespan is
   incredible, the endless list of modules by contributors, all the open
   source even non-open source projects done with Python is incredible.
   **
   And since Python 3.10 exists Python 4 seems very far away but only time
   may show what will happen. Maybe even a bigger community, even children
   and elderly being able to make stuff.
