Question

Assertion (A): [1,2,3]+‘123’ is an invalid expression in Python.

Reason (R): In Python, a list cannot be concatenated with a string.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation for Assertion (A).

• Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation for Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation for Assertion (A).

Explanation:

In Python, the + operator performs concatenation only when both operands are of the same data type. Since [1, 2, 3] is a List and '123' is a String, attempting to add them results in a TypeError, making the expression invalid as stated.
