Python | Pandas Series.nbytes

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.nbytes attribute is return the number of bytes required to store the underlying data in the given Series object.

Syntax:Series.nbytes

Parameter : None

Returns : number of bytes

Example #1: Use Series.nbytes attribute is used to find the number of bytes required to store the underlying data of the given Series object.

# importing pandas as pd
import pandas as pd

# Creating the Series
sr = pd.Series(['New York', 'Chicago', 'Toronto', 'Lisbon', 'Rio'])

# Creating the row axis labels
sr.index = ['City 1', 'City 2', 'City 3', 'City 4', 'City 5']

# Print the series
print(sr)

Output :

Now we will use Series.nbytes attribute to find the number of bytes required to store the underlying data of the given Series object.

# return the number of bytes
sr.nbytes

Output :

As we can see in the output, the Series.nbytes attribute has returned 40 indicating that the memory needed to store the given series object is 40 bytes.

Example #2 : Use Series.nbytes attribute is used to find the number of bytes required to store the underlying data of the given Series object.

# 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.nbytes attribute to find the number of bytes required to store the underlying data of the given Series object.

# return the number of bytes
sr.nbytes

Output :

As we can see in the output, the Series.nbytes attribute has returned 32 indicating that the memory needed to store the given series object is 32 bytes.
