c) One teacher of mine said to me that python is far more better than perl!?!?

Is this a college level professor? Every language has it's pros and cons. I really doubt any language qualifies as a much better than any other, although there are a few that come to mind, and there are others that are just inherently a mess. Despite the fact that I absolutely hated the Prologue and Lisp programs I wrote in college, I have to admit that they have their place, and certainly have advantages in many respects.

Now if (s)he were just taking a jab at Perl there really isn't anything wrong with that, hell I do it with Fortran all the time, but anyone who seriously believes one language is "far better" than another is probably not a very seasoned programmer.
