I stumbled upon it, too.
2**2**2**2 == 2**(2**(2**2)) == 2**16 == 65536

"... in an unparenthesized sequence of power and unary operators, the
operators are evaluated from right to left ..."

So, 2**2**

Exponentiation is right-associative. 2**2**2**2 = 2**(2**(2**2))
I have a simple program and the output isn't what I expect. Could
somebody please explain why?
Here's the code:
#simple program
print "v = 2"
v = 2
print "v**v = 2**2 =", v**v
print "v**v**v = 2**2**2 =", v**v**v
print "v**v**v**v = 2**2**2**2 =", v**v**v**v
#end program
Here's the output:
>>>
