dear Kamil_Rizvi.
thank you for your posting.
Basically, anaconda and its tools are not updated automatically. Of course, it is also possible to install automatically using a shell script.
why are you doing that? Let me explain.
Areas such as computer-assisted data science are still new fields of technology (although scientifically, because of statistics, it’s been around for 200 years). In such areas, frequent program updates make registry management and version control complicated.
Therefore, updating the program is delegated to the user.
Please see the following site for how to upgrade python in anaconda.
Regards, you.
