Python Pandas — I — Question 4

(a)

Series([], dtype: int64)

The slice S[1:1] starts at index 1 and ends at index 1, but because the end index is exclusive, it does not include any elements, resulting in an empty Series.

(b)

pencils    20
dtype: int64

The slice S[0:1] starts at index 0 and ends at index 1, but because the end index is exclusive, it includes only one element i.e., the element at index 0.

(c)

pencils      20
notebooks    33
dtype: int64

The slice S[0:2] starts at index 0 and ends at index 1, hence, it includes two elements i.e., elements from index 0 and 1.

(d)

pencils      12
notebooks    12
scales       52
erasers      10
dtype: int64

The slice S[0:2] = 12 assigns the value 12 to indices 0 and 1 in Series S, directly modifying those elements. The updated Series is then printed.

(e)

Index(['pencils', 'notebooks', 'scales', 'erasers'], dtype = 'object')
[20 33 52 10]

The code print(S.index) displays the indices of Series S, while print(S.values) displays the values of Series.
