```
## Library usage
```python
from web3 import Web3
from web3.providers.auto import load_provider_from_environment
from eth_tools.block_iterator import BlockIterator
provider = load_provider_from_environment()
web3 = Web3(provider)
block_iterator = BlockIterator(web3, start_block=10_000_000, end_block=10_000_999)
for block in block_iterator:
print(block.number)
