word = "Python"

# Strings are iterable
for letter in word:
    print(letter)

print('=' * 10)

# Create an iterator
word_iterator = iter("Jo")

print(next(word_iterator))
print(next(word_iterator))

# Differences Between Iterables and Iterators

In Python, an `iterable` refers to any object, like a list, tuple, or string, that can return its elements one at a time and thus is considered a **repeatable object**.

Iterables can be used in `for` loops and with functions like `list()`, `set()`, and `tuple()`.

```python title="Example of an Iterable"
# A list is an iterable
my_list = [1, 2, 3]

# A list is a repeatable object
for item in my_list:
    print(item)
```

<br />

On the other hand, an `iterator` is an object that allows us to traverse through all the elements of an iterable **one element at a time**.

An iterator can be created from an iterable using the `iter()` function, and we can access the next element using the `next()` function.

```python title="Example of an Iterator"
# A list is an iterable
my_list = [1, 2, 3]

# Creating an iterator
my_iterator = iter(my_list)

# Access the next element
print(next(my_iterator))  # 1
print(next(my_iterator))  # 2
print(next(my_iterator))  # 3
```

An iterable is a data type that can be traversed using a `for` loop or functions like `list()`, `set()`, `tuple()`. An iterator is created with the `iter()` function and accesses elements using the `next()` function.
