How to flatten a record to dataframe in dask.
Dask arrays outline an outsized array with a grid of blocks of smaller arrays. we will flatten down this list by using list.flatten(). This technique can flatten a multi-dimensional array in python. These strategies are fairly new and solely works within the latest versions of recent browsers.
Step 1- Importing Libraries.
Before importing Libraries, sometimes We have to install their packages.
#! pip install dask[bag]
import dask.bag as db
Step 2- Making a 2D list.
We will create a sample 2D list so that we can flatten it.
a = db.from_sequence([[1], [2, 3],[1,2,3,4,5,6,7]])
list(a)
Step 3- Flattening the list.
Now applying the provided function by Dask to the Sample array.
list(a.flatten())
