Python | Pandas Series.iloc

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.iloc

attribute enables purely integer-location based indexing for selection by position over the given Series object.

Syntax:Series.iloc Parameter : None Returns : Series
Example #1:

Use

Series.iloc

attribute to perform indexing over the given Series object.

Python3
# 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.iloc

attribute to perform indexing over the given Series object.

Python3 1==
# slice the object element in the 
# passed range
sr.iloc[0:2]
Output :

As we can see in the output, the

Series.iloc

attribute has returned a series object containing the sliced element from the original Series object.

Example #2 :

Use

Series.iloc

attribute to perform indexing over the given Series object.

Python3
# importing pandas as pd
import pandas as pd

# Creating the Series
sr = pd.Series(['1/1/2018', '2/1/2018', '3/1/2018', '4/1/2018'])

# Creating the row axis labels
sr.index = ['Day 1', 'Day 2', 'Day 3', 'Day 4']

# Print the series
print(sr)
Output :

Now we will use

Series.iloc

attribute to perform indexing over the given Series object.

Python3 1==
# slice the object element in the 
# passed range
sr.iloc[1:3]
Output :

As we can see in the output, the

Series.iloc

attribute has returned a series object containing the sliced element from the original Series object.
