Question

What will be the output of the following Python code?

import pandas as pd 
dd = {'One':1, 'Two':2, 'Three':3, 'Seven':7} 
rr = pd. Series (dd) 
rr ['Four'] = 4 
print (rr)

Options

• One 1
  Two 2
  Three 3
  Seven 7
  dtype: int64

• One 1
  Two 2
  Three 3
  Four 4
  Seven 7
  dtype: i.n64

• Four 4
  One 1
  Two 2
  Three 3
  Seven 7
  dtype: in64

• One 1
  Two 2
  Three 3
  Seven 7
  Four 4
  dtype: in64

Answer 1

One 1
Two 2
Three 3
Seven 7
Four 4
dtype: in64

Explanation:

• The pd.Series() function converts the dictionary dd into a pandas Series object (rr). 
• The rr['Four'] = 4 statement creates a new key '!four' with the value 4 in the Series rr. 
• The dictionary keys serve as index labels for the series. 
• Series values are derived from dictionary values. 
• The new key-value pair 'Four': 4 is displayed at the conclusion of the Series.
