Converting a pandas DataFrame into a Dask DataFrame

Dask DataFrames are implemented based on pandas DataFrames. For data analysts, it is necessary to learn how to convert a Dask DataFrame into a pandas DataFrame. Take a look at the following code:

# Import Dask DataFrame
from dask import dataframe as dd

# Convert pandas dataframe to dask dataframe
ddf = dd.from_pandas(pd_df,chunksize=4)

type(ddf)

This results in the following output:

dask.dataframe.core.DataFrame

Here, we have used the from_pandas() method to convert a pandas DataFrame into a Dask DataFrame.
