Which language to learn?

I know that this has to be a quite frequently asked question, but a group only gets more valuable members by helping people who want to learn. Currently I'm sort of proficient with DOS commands. Obviously you cannot create a complicated graphical program out of DOS. I've heard all over this board that Python sucks, which ironically is the one language most of my friends recommended learning. What language can I learn that is actually useful?

I come to /prog/ for you guys are the only assholes on the internet that will bash other languages if they do suck. Forums have to be 'unbiased' and 'neutral'.

What is the difference between strong typing and static typing, or whichever the two options are?
It's Strong vs. Weak.... otherwise known as Static vs. Dynamic.

Basically, a Weakly type (aka Dynamic) language allows you to directly mix operations between variables of different types.  (ie. you can treat a string of text containing "1500" as if it were an integer whose value is 1500).
