Python Coding Challange - Question With Answer(01261224)

 

Step 1: Create a list

data = [1, 2, 3]

This creates a list named data with three elements: $1, 2, 3$.

---

Step 2: Unpack the list into a set

output = {*data, *data}

Here:

• The unpacking operator * is used with the list data. It extracts the elements $1, 2, 3$ from the list.
• {*data, *data} means the unpacked elements of the list are inserted into a set twice. However:
  • Sets in Python are unordered collections of unique elements.
  • Even though the elements $1, 2, 3$ are unpacked twice, the set will only store one copy of each unique value.

Result:

output = {1, 2, 3}

---

Step 3: Print the set

print(output)

The print statement outputs the set output:

{1, 2, 3}

---

Key Points to Remember:

1. The unpacking operator * extracts elements from an iterable (like a list, tuple, or set).
2. A set is a collection of unique elements, so duplicates are automatically removed.
3. Even though *data is unpacked twice, the final set contains only one instance of each value.

Output:

{1, 2, 3}
