Optimize Parallel Execution in Python with 'KMP_BLOCKTIME' and 'OMP_NUM_THREADS'

These lines of code set environment variables in Python using the 'os.environ' dictionary.

The first line sets 'KMP_BLOCKTIME' to '0'. This variable, used by Intel's OpenMP runtime library, controls thread scheduling behavior. Setting it to 0 instructs the library to employ a more aggressive thread scheduling strategy.

The second line sets 'OMP_NUM_THREADS' to '1'. This variable, also used by OpenMP, specifies the number of threads for parallel execution. By setting it to 1, you instruct OpenMP to use only a single thread for parallelism.

These environment variables are useful for controlling parallel execution behavior within your code. However, they are specific to Intel's OpenMP runtime library and might not have any effect if using a different compiler or runtime library.
