What does next build-in function mean in python3?

Question

So what does next keyword mean in python 3? I am using 3.4.0 and sublime 3 text editor and when I write next in it it turns blue? I tried to search about it but I haven't seem to find anything more specific.

Answer 1

next is not a keyword but a built-in function .

The Python documentation also includes a list of keywords ; you'll see it is not listed there.

In Python 2, iterators defined an iterator.next() method , but that has been renamed to iterator.__next__() in Python 3. It is probably that method name the syntax highlighter tries to color-code; the Python 3 package for Sublime Text adds __next__ as highlighted too.
