Python 3.13.0 : know this -OOt ?

Today, I follow the actions from NEMO the basic explorer files from linux and I found this: -OOt

This first source code:

#!/usr/bin/python3 -OOt

... this is new, and refers to Python compiler optimizations.

The -OOt par in the shebang line #!/usr/bin/python3 -OOt refers to Python compiler optimizations:

1. -O: This flag enables basic optimizations. It tells the Python compiler to optimize constants and global variables.
2. -O2: This flag enables more aggressive optimizations. It applies additional compiler passes to further optimize the code .
3. -Ot: This flag optimizes for size. It reduces memory usage by eliminating unused variables and dead code.

So, -OOt combines three levels of optimization:

• Basic optimization (-O)
• More aggressive optimization (-O2)
• Optimization for size (-Ot)
