Assertion (A): List traversal in Python is done through slicing and using for loop also.
Reasoning (R): Traversal can be done only through forward indexing.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.

Answer
A is true but R is false.
Explanation
List traversal in Python can be done using slicing and a for loop. Both methods allow to access and iterate over elements in a list. Traversal in Python lists can be done through both forward and backward indexing.

Assertion (A): List in Python is a collection of values of any type.
Reasoning (R): In lists, you can change the elements of a list in place.

Consider the given two statements:
T1 = [3, 9, 0, 1, 7]
T2 = [5, 1, 0, 7, 5.5]Assertion (A): Output of
print(len(T1) == len(T2))is True.Reasoning (R): The
len()function returns the number of elements in the list. If two lists have same number of elements, then==operator will return True.- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.

Assertion (A): In Python, list is an immutable collection of data.
Reasoning (R): Mutable means that any change or alteration in data is mentioned in the same place. The updated collection will use the same address for its storage.

Assertion (A): The position of each element in the list is considered as its index.
Reasoning (R): Indexing in a list can be positive and negative; index is defined using [] brackets.
