The ** operator:

Question

Options

• Aperforms duplicated multiplication
• Bdoes not exist
• Cperforms oating-point multiplication
• Dperforms exponentiation

• A
  6% (1)
• B
  11% (2)
• C
  6% (1)
• D
  78% (14)

Explanation

In Python, ** is the exponentiation operator, meaning it raises the left operand to the power of the right operand - for example, 2 ** 3 evaluates to 8 (2 raised to the power of 3). Option A is wrong because "duplicated multiplication" isn't a real operation, and while exponentiation can be thought of as repeated multiplication, that's not what the operator is called. Option B is simply false - ** absolutely exists in Python (and many other languages). Option C is wrong because ** works with both integers and floats, and floating-point multiplication is handled by the regular * operator.

Memory tip: Think of the two stars as a "power tower" - the second * is stacked on top of the first, just like how exponentiation "stacks" multiplication on top of itself. 2 ** 3 = "2, three levels high" = 8.
