zip(*iterables) Make an iterator that aggregates elements from each of the iterables. Returns an iterator of tuples, where thei-th tuple contains thei-th element from each of the argument sequences or iterables. The iterator stops when the shortest input iterable is exhausted. With a sing...
Python has a set of built-in functions. FunctionDescription abs()Returns the absolute value of a number all()Returns True if all items in an iterable object are true any()Returns True if any item in an iterable object is true ascii()Returns a readable version of an object. Replaces none...

Can I create my built-in functions? No, you cannot create your built-in function. But, Python allows a user to create user-defined functions. How do I use built-in functions? Using a built-in function is very simple, call it by its name followed by parentheses, and pass the required...
