Python | Pandas Series.ix
  • Last Updated : 28 Jan, 2019

Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.

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.ix attribute is a primarily label-location based indexer, with integer position fallback. It takes the label as input and returns the value corresponding to that label.

Syntax:Series.ix

Parameter : None



Returns : value

Example #1: Use Series.ix attribute to return a value lying at the specified label in the given Series object.

# importing pandas as pd
import pandas as pd
  
# Creating the Series
sr = pd.Series(['New York', 'Chicago', 'Toronto', 'Lisbon'])
  
# Creating the row axis labels
sr.index = ['City 1', 'City 2', 'City 3', 'City 4'
  
# Print the series
print(sr)

Output :

Now we will use Series.ix attribute to return the value lying corresponding to the ‘City 4’ label.
