Python | Pandas Series.dtype
  • 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.dtype attribute returns the data type of the underlying data for the given Series object.

Syntax: Series.dtype

Parameter : None



Returns : data type

Example #1: Use Series.dtype attribute to find the data type of the underlying data for 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.dtype attribute to find the data type of the given Series object.




# return the data type
sr.dtype

Output :

As we can see in the output, the Series.dtype attribute has returned ‘O’ indicating the data type of the underlying data is object type.



Example #2 : Use Series.dtype attribute to find the data type of the underlying data for the given Series object.




# importing pandas as pd
import pandas as pd
  
# Creating the Series
sr = pd.Series([1000, 5000, 1500, 8222])
  
# Print the series
print(sr)

Output :

Now we will use Series.dtype attribute to find the data type of the given Series object.




# return the data type
sr.dtype

Output :

As we can see in the output, the Series.dtype attribute has returned ‘int64’ indicating the data type of the underlying data is of int64 type.
