Question

Extracting a part of a series can be done through .

• A. Indexing
• B. Subtracting
• C. Slicing
• D. Partitioning

Hint:

A part of a series is extracted by slicing. Use s[a:b].

Answer 1

The Correct Option is C

Step 1: Idea:
Think of what you would do in Python to get a few consecutive items out of a series. You write a range such as s[a:b], and that range notation has a fixed name.

Step 2: Name the operation behind the range notation.
The notation s[start:stop] returns a smaller series made of the items between the two limits. This operation is called slicing.

Step 3: Remove the options that do not fit.
Indexing returns one item, not a part. Subtracting is arithmetic. Partitioning is not a standard Pandas term for this task.

Step 4: Match with the remaining option.
Only slicing returns a sub-series, so it is the answer.

Step 5: Test every option against the result.
Option 1: Indexing gives one item, so it fails the word 'part'.
Option 2: Subtracting is a maths action between numbers, so it cannot cut out items.
Option 3: Slicing gives a sub-series between two limits, so it fits.
Option 4: Partitioning is not a Pandas word for picking items, so it fails.

Step 6: Conclusion.
The correct term is slicing, option 3. \[ \boxed{3} \]
