What does the ** maths operator do in Python?

Question

What does this mean in Python:

sock.recvfrom(2**16)

I know what sock is, and I get the gist of the recvfrom function, but what

Answer 1

It is the power operator.

From the Python 3 docs:

The power operator has the same semantics as the built-in pow() function, when called with two arguments: it yields its left argument raised to the power of its right argument. The numeric arguments are first converted to a common type, and the result is of that type.

It is equivalent to 2¹⁶ = 65536, or pow(2, 16)

Answer 2

I believe that's the power operator, such that 2**5 = 32.

Answer 3

2 raised to the 16th power

Answer 4

It is the awesome power operator which like complex numbers is another thing you wonder why more programming languages don't have.

Answer 5

a ** b  =  pow(a,b)
