What will be the output of 'print(2 ** 3)' in Python?

The expression '2 ** 3' in Python uses the exponentiation operator '**', which raises the number on the left (the base, which is 2) to the power of the number on the right (the exponent, which is 3). This means you multiply 2 by itself 3 times:

2 ** 3 = 2 * 2 * 2 = 4 * 2 = 8.

Thus, the output of this expression is 8, making the correct answer B. This is consistent with how exponentiation works in mathematics, where raising a number to an exponent indicates repeated multiplication of that number.
