And run the configure command to verify if all the dependencies are met for the Python installation.

cd Python-3.10.11

./configure --enable-optimizations

Let's get the number of CPU cores your machine has,

nproc

This will print a number, use that in the below command, make will start the build process and the number 4 represents the number of CPU cores.

make -j 4 

Make install The default Python installation is /usr/bin. If you want to install Python under /usr/local/bin instead of overwriting the default, do this:

make altinstall
