How do you iterate over an object in Python?

Iterator in python is an object that is used to iterate over iterable objects like lists, tuples, dicts, and sets. The iterator object is initialized using the iter() method. It uses the next() method for iteration. next ( __next__ in Python 3) The next method returns the next value for the iterable.

How do you iterate over an array?

Iterating over an array You can iterate over an array using for loop or forEach loop. Using the for loop − Instead on printing element by element, you can iterate the index using for loop starting from 0 to length of the array (ArrayName. length) and access elements at each index.

How do you access an array of elements in Python?

We can access elements of an array using the index operator [] . All you need do in order to access a particular element is to call the array you created. Beside the array is the index [] operator, which will have the value of the particular element’s index position from a given array.

What does __ ITER __ do in Python?

The __iter__() function returns an iterator for the given object (array, set, tuple, etc. or custom objects). It creates an object that can be accessed one element at a time using __next__() function, which generally comes in handy when dealing with loops.

What line of code is used to iterate through all the properties of an object?

The for…in statement iterates over all enumerable properties of an object that are keyed by strings (ignoring ones keyed by Symbols), including inherited enumerable properties.

Which construct provides an easy way to iterate over arrays?
