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.keys()
function is an alias for index. It returns the index labels of the given series object.
Syntax: Series.keys()
Parameter : None
Returns : index
Example #1: Use Series.keys()
function to return the index labels of the given series object.
# importing pandas as pd import pandas as pd # Creating the Series sr = pd.Series([ 10 , 25 , 3 , 25 , 24 , 6 ]) # Create the Index index_ = [ 'Coca Cola' , 'Sprite' , 'Coke' , 'Fanta' , 'Dew' , 'ThumbsUp' ] # set the index sr.index = index_ # Print the series print (sr) |
Output :
Now we will use Series.keys()
function to return the index labels of the given series object.
# return the keys result = sr.keys() # Print the result print (result) |
Output :
As we can see in the output, the Series.keys()
function has returned all the index labels of the given series object.
Example #2 : Use Series.keys()
function to return the index labels of the given series object.
# importing pandas as pd import pandas as pd # Creating the Series sr = pd.Series([ 11 , 21 , 8 , 18 , 65 , 84 , 32 , 10 , 5 , 24 , 32 ]) # Create the Index index_ = pd.date_range( '2010-10-09' , periods = 11 , freq = 'M' ) # set the index sr.index = index_ # Print the series print (sr) |
Output :
Now we will use Series.keys()
function to return the index labels of the given series object.
# return the keys result = sr.keys() # Print the result print (result) |
Output :
As we can see in the output, the Series.keys()
function has returned all the index labels of the given series object.
