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.
Installation
pip install shuffled
Usage
Example: Generating a permutation of integers.
>>> from shuffled import Shuffled
>>> 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]
Example: Listing all IP addresses in a subnet in random order.
>>> import ipaddress
>>> from shuffled import Shuffled
>>> network = ipaddress.IPv4Network('10.0.0.0/8')
>>> shuffled_range = Shuffled(network.num_addresses)
>>> for index in shuffled_range:
... print(network[index])
