How to build a function to decode the classic Elias code if the direct encoding works correctly?

Question

Python

Hello everyone, Elias's classic code's direct encoding function is OK, everything works:

return (int(log(int(log(number,2)),2))*'0'+' '+str(bin(int(log(number,2))+1))[2:]+' '+str(bin(number)[3:]))

but I don’t know how to do the opposite .. conditionally from 000100110001110 to 398. Help me out)

Answer 1

Describe in words what this encoding does, what does it write to the file?
And read this:
1) count how many zeros go at the beginning of the string.
2) This is how many bits you need to read further and translate into a decimal number system.
3) This is as many bits as you need to read further and convert to the decimal system in order to decode the number.
