What does this mean in python:
sock.recvfrom(2**16)
I know what sock is and I get the jest of recvfrom function, but what the hell is 2**16?

It is the power operator, see this reference:

It is equivalent to 216 = 65536

In Python (the scope of the OP's) question, 2 ** 16 evaluates to 65536, while 2 ^ 16 evaluates to 18. You appear to attach a strange meaning to "is equivalent to".

@John: That is why he didn't actually post "2 ^ 16" -_-

@Pynt: You are gravely mistaken, @rossoft did actually post "2 ^ 16"; subsequent to my comment, @kaiser.se edited the answer to read what you see now, effectively 2<superscript>16</superscript>. You can verify this by clicking on the clickable part of "edited N hours ago".

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