New to working with APIs, any good tutorials/books/guides?

Er, first you learn how to program in Python, then you read the API
documentation and do what it says. If the documentation says that the
function requires a single string argument, then you give the function a
single string argument.
I suspect that either your question is much more subtle and complicated
than your actual words allow, or you're making things much, much, much
more complicated than they actually are. In an earlier post, you said you
had some experience programming in Python. If your code works, then you
know how to use the APIs of the functions and libraries that you used.
Here I am using the API for the len() function:
alist = [1, 2, 3]
number_of_items = len(alist)
That's all. Easy, wasn't it? I'm using the API for the len() function.
If you were asking for help with some *specific* API ("I don't understand
the multiprocessing module!"), that I could get. Some APIs are
complicated, or badly designed, or badly written, or require advanced
understanding. But APIs *in general* can be as simple as len().

If an API is defined for a C library or function, then, no, you can't use
it in Python, or Lisp, or Ruby, just as you can't use a Lisp function in
C or Forth or Pascal. Not unless one or the other language makes special
provision to allow such cross-language communication.
It might be better for you to give us concrete examples of what you don't
understand, rather than to continue talking in vague generalities.
