API stands for "Application Programming Interface", and it essentially means the set of interfaces, calling conventions, functions, methods etc. of a language, library or even a single function. For example, in Python, the API of the len() function is really simple: - len() takes a single mandatory argument; - that argument must be a sequence, mapping, or some other object with a __len__ method; - otherwise len() will raise TypeError; - len() will always return an int; - which is supposed to be the length of the sequence or mapping. That's pretty much the API for the function len(). Simple, isn't it? Now, obviously the API for an entire library is more complicated. It includes rules for how many and what kind of arguments each function, class or method expects; what values they are allowed to be; what sort of values will be returned; what exceptions will be raised, and so forth. Basically, when you read the manual for a language or library, that's documenting the API. That's all there is to it. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
