Converting an 8-bit binary to decimal WITHOUT the shortcuts

[EIA]

Hey everyone, I am trying to self-teach myself in python and I was wondering. Is there a way to convert an 8-bit binary to decimal without using the shortcuts? I don't have any code for this yet because I wouldn't even know where to start beside get the input via possibly strings or integers. I'm using python 3.x also.

Any help would be awesome.

Have you tried converting them manually on paper? If not, this is a good place to start.

Having understood that, you can try convert that into a python.

If not

>>> int(bin(8)[2:], 2)
8

Of course there is. It probably run slower then builtin.

Make a string.
Loop through with enumerate.
add bit shift value against length of string - enumerate + 1 to total

I understand how to convert them on paper, I'm just a bit confused on how to convert the string into each binary number. Also, I'm trying to learn everything with less shortcuts. If I can do it without shortcuts I can easily explain it with shortcuts later down the road

I'm just a bit confused on how to convert the string into each binary number.

you can iterate over a string or convert it to list with built-in function and iterate over that list

Try following these simple steps:

1. Write out steps for doing it manually
   
2. Try writing code that does the same thing
   
3. Post here if you run into a specific problem
