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.hasnans
attribute returns a boolean value. It return True
if the given Series object has missing values in it else it return False
.
Syntax:Series.hasnans
Parameter : None
Returns : boolean
Example #1: Use Series.hasnans
attribute to check if the given Series object has any missing values in it.
import pandas as pd
sr = pd.Series([ 'New York' , 'Chicago' , 'Toronto' , 'Lisbon' ])
sr.index = [ 'City 1' , 'City 2' , 'City 3' , 'City 4' ]
print (sr)

Output :
Now we will use Series.hasnans
attribute to check for the missing values in sr object.
Output :
As we can see in the output, the Series.hasnans
attribute has returned False
indicating that there is no missing values in the given series object.
Example #2 : Use Series.hasnans
attribute to check if the given Series object has any missing values in it.
import pandas as pd
sr = pd.Series([ 1000 , 'Calgarry' , 5000 , None ])
print (sr)
|
Output :
Now we will use Series.hasnans
attribute to check for the missing values in sr object.
Output :
As we can see in the output, the Series.hasnans
attribute has returned True
indicating that there is at least one missing value in the given series object.
