Python3.12.2 not getting updated in Ubuntu successfully

I'm a new user in Ubuntu, new in Linux domain. I have python3.10 as the system version. I have been trying to update to 3.12.2. I downloaded the python3.12.2 file from python.org. After that, I followed some steps which I think that entirely messed my system. I am sharing those steps if this help anybody in future can avoid.

Step 1:

tar -xf Python-3.10.2.tgz   # Replace "Python-3.10.2.tgz" with the name of the downloaded filecd Python-3.10.2./configuremakesudo make install

First Error :

configure: error: in `/home/user/Downloads/Python-3.12.2':configure: error: no acceptable C compiler found in $PATHSee `config.log' for more details

Step 2:To resolve it, I did the following:

sudo apt updatesudo apt install build-essential

Step 3:

cd /path/to/Python-3.12.2 ./configuremake sudo make install 

Error: After the make command, everything went to hell!

Step 4:To resolve the above issue, I tried this:

sudo apt updatesudo apt install libssl-dev

Error: Nothing resolved. No luck

Step 5:Tried to update interpreter from pycharm. No luck.Meanwhile, my pip and python3 returning two separate locations!

After all these, my machine was going all different directions. Reinstalled ubuntu again and back to 3.10
