2d game development

In school we started to learn how to write 2d games using the c++ libraries Allegro adn SDL. Now, I was wondering which library is more suited for writing 2d games? And are there not lots of other libraries out there, are any of those better?

I am basically asking what libraries is most suited for writing 2d games because I don't want to be thoought some lame method in school so that I will have to get used to another way later in my life because what I was thought wasn't good.
Now I will most certinaly have to learn more and perhaps something else later on anyway, but you might understand that I don't want to study something useless.

When I first came here nobody was a python supporter (or atleast if they were, they kept it as a deep dark shameful secret).
