Explanation:
๐ธ 1. List Creation
clcoding = [1, 2, 3]
A list named clcoding is created.
It contains three elements: 1, 2, and 3.
Lists in Python are mutable, meaning they can be changed.
๐ After this line:
clcoding = [1, 2, 3]
๐ธ 2. Using append() Method
clcoding.append(4)
The append() method adds an element to the end of the list.
Here, 4 is added.
๐ After execution:
clcoding = [1, 2, 3, 4]
๐ธ 3. Important Concept: Return Value of append()
The append() method does NOT return the updated list.
It modifies the list in place.
It returns None.
๐ธ 4. Print Statement
print(clcoding.append(4))
First, clcoding.append(4) is executed → list becomes [1, 2, 3, 4]
Then print() prints the return value of append(), which is:
None
๐ธ 5. Final Output
None
