# Shuffled: Random iterators for large integer ranges
Shuffled is a library for iterating randomly and without repetition over integer ranges.
It doesn't store all the integers in memory so that you can work with ranges of up to
2128 elements, even with your standard RAM available.
```python
>>> shuffled_range = Shuffled(10)
>>> list(shuffled_range)
[4, 1, 2, 9, 8, 5, 3, 0, 6, 7]
>>> same_shuffled_range = Shuffled(10, seed=shuffled_range.seed)
>>> list(same_shuffled_range)
[4, 1, 2, 9, 8, 5, 3, 0, 6, 7]
```
```python
>>> network = ipaddress.IPv4Network('10.0.0.0/8')
>>> shuffled_range = Shuffled(network.num_addresses)
>>> for index in shuffled_range:
... print(network[index])
