Delaying functions
You have been tasked with adding up your company's costs for the last 2 weeks. Because you know that you will want to run this same computation in the future with many more weeks, you think it might be a good idea to write it in a way that can be parallelized.
The arrays of costs of items for the last two weeks are available as costs_week_1 and costs_week_2, and numpy has been imported as np.
Cet exercice fait partie du cours
Parallel Programming with Dask in Python
Instructions
- Import the
delayed()function. - Delay the
np.sum()function and use it to create delayed sums ofcosts_week_1andcosts_week_2. - Add the two sums together to create another delayed object of the total.
- Compute and print this total.
