Parallel programming solves big numerical problems by dividing them into smaller sub-tasks, and hence reduces the overall computational time on multi-processor and/or multi-core machines. Traditionally, Python is considered to not support parallel programming very well, partly because of the global interpreter lock (GIL). nprocs = mp.

“As code” means simplifying complex and time-consuming tasks by automating some, or all, of their processes. As a result, IT teams often end up performing time-consuming, manual processes. This can cause performance and security issues — in turn, costing organizations time and money. IAC is just the beginning.
