Python | Pandas Series.as_blocks()

Pandas series is a One-dimensional ndarray with axis labels. The labels need not be unique but must be a hashable type. The object supports both integer- and label-based indexing and provides a host of methods for performing operations involving the index.

Pandas Series.as_blocks() function is used to convert the frame to a dict of dtype -> Constructor Types that each has a homogeneous dtype.

Syntax: Series.as_blocks(copy=True)



Parameter :
copy : boolean, default True

Returns : values : a dict of dtype -> Constructor Types

Example #1: Use Series.as_blocks() function to return the given series object as a dictionary.

# importing pandas as pd
import pandas as pd
  
# Creating the Series
sr = pd.Series(['New York', 'Chicago', 'Toronto', 'Lisbon', 'Rio'])
  
# Create the Index
index_ = ['City 1', 'City 2', 'City 3', 'City 4', 'City 5'
  
# set the index
sr.index = index_
  
# Print the series
print(sr)

Output :

City 1    New York
City 2     Chicago
City 3     Toronto
City 4      Lisbon
City 5         Rio
dtype: object

Now we will use Series.as_blocks() function to return the given series object as a dictionary.
