"h" means a short int, or 16-bit int. "<" means use little-endian. | [Kevin Burke's answer](https://stackoverflow.com/a/1698048/8008041) to this question works great when your binary string represents a single short integer, but if your string holds binary data representing multiple integers, you will need to add an additional 'h' for each additional integer that the string represents. ... |

"h" means a short int, or 16-bit int. "<" means use little-endian. | ```py
int(value[::-1].hex(), 16)
```
By example:
```py
value = b'\xfd\xff\x00\x00\x00\x00\x00\x00'
print(int(value[::-1].hex(), 16))
65533
```
`[::-1]` invert the values (little endian), `.hex()` trabnsform to hex literal, `int(,16)` transform from hex literal to int base16. |
