**What do you like best about mpi4py?**

mpi4py has been of great use when dealing with problems that are computationally intensive in my Python projects.  Due to parallel processing, I can reduce the amount of time taken to perform certain demanding simulations and data analysis.

**What do you dislike about mpi4py?**

One problem with using parallel code is that it can be tricky to spot and solve any problems within the parallel code.  Finally, the debugging of data transmission is complex because there are limited tools for pointing out errors between processes.

**What problems is mpi4py solving and how is that benefiting you?**

mpi4py helps me deal with parallel computing with the help of tools that are specially designed for my python based environment.  This means that for tasks that require a considerable amount of computing power I was able to work much faster on simulations as well as analysis.
