[docs] Section 5 of Python 2.7.16 documentation errors

[Bud Maddock]

Most notable, section 5. Expressions

def f(a,b):

     print a,b  # raises an error and should read print(a,b)


Section 5.4  Raising a negative number to a fractional power does not 
return an error as stated in the documentation but appears to 
functioning correctly.


Section 5.9  <> returns a syntax error and is no longer usable to replace !=
