Similar to, use the same approach to compute pi using mpi4py. As previously, the worker process identifies the region under the function 1+x2 for its associated portion. The number of processes is broadcast to all workers, who may then calculate their parts using the function calc pi. The root process then adds all of the results from the workers using the reduce operation and outputs the result. It is worth noting that in the reduction operation, we may indicate what to do with the obtained data.
