C# short/long/int literal format?
...float
var m = 1.0m; // decimal
var i = 1; // int
var ui = 1U; // uint
var ul = 1UL; // ulong

Convert base-2 binary number string to int
...g import BitArray
>>> b = BitArray(bin='11111111')
>>> b.uint
255
Note that the unsigned integer is different from the signed integer:
>>> b.int
-1
The bitstring module isn't a requirement, but it has lots of performant methods for turning input into and from bits int...
