`urandom_range()` is not a standard function in Python, but it could possibly refer to a custom function that generates a random integer within a specified range using the `urandom()` function from the `os` module.
Here is an example implementation of `urandom_range()`:
```python
import os
def urandom_range(start, stop):
range_size = stop - start
bytes_needed = (range_size.bit_length() + 7) // 8
random_bytes = os.urandom(bytes_needed)
random_int = int.from_bytes(random_bytes, byteorder='big')
return start + random_int % range_size
```
This function takes in two arguments, `start` and `stop`, representing the inclusive range of integers to generate. It first calculates the size of the range and the number of bytes needed to represent all integers in that range. It then generates random bytes using `os.urandom()` and converts them into an integer. Finally, it returns a random integer within the specified range by taking the modulus of the generated integer with the size of the range and adding the starting value.
