Python | Pandas Series.multiply()
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.multiply() function perform the multiplication of series and other, element-wise. The operation is equivalent to series * other, but with support to substitute a fill_value for missing data in one of the inputs.
Syntax: Series.multiply(other, level=None, fill_value=None, axis=0)
Parameter :
other : Series or scalar value
fill_value : Fill existing missing (NaN) value
level : Broadcast across a level,Returns : result : Series
Example #1: Use Series.multiply() function to perform the multiplication of a scalar with the given series object.
# importing pandas as pdimport pandas as pd # Creating the Seriessr = pd.Series([10, 25, 3, 11, 24, 6]) # Create the Indexindex_ = ['Coca Cola', 'Sprite', 'Coke', 'Fanta', 'Dew', 'ThumbsUp'] # set the indexsr.index = index_ # Print the seriesprint(sr) |
Output :
Now we will use Series.multiply() function to perform the multiplication of scalar with the series.
# multiply the given value with seriesresult = sr.multiply(other = 10) # Print the resultprint(result) |
Output :
As we can see in the output, the Series.multiply() function has returned the result of multiplication of the given scalar with the series object.
Example #2: Use Series.multiply() function to perform the multiplication of a scalar with the given series object. The given series object contains some missing values.
# importing pandas as pdimport pandas as pd # Creating the Seriessr = pd.Series([19.5, 16.8, None, 22.78, None, 20.124, None, 18.1002, None]) # Print the seriesprint(sr) |
Output :
Now we will use Series.multiply() function to perform the multiplication of scalar with the series.
# multiply the given value with series# fill 5 at the place of all the missing valuesresult = sr.multiply(other = 10, fill_value = 5) # Print the resultprint(result) |
Output :
As we can see in the output, the Series.multiply() function has returned the result of multiplication of the given scalar with the series object.
