ord(ch) turns a character into an integer, i.e. ord('a') = 97, etc.
You can use the << (left shift), >> (right shift), | (logical or),
and & (logical and) operations just like in C.
So for your diagram
|-------------bits(1-8)-----------|
Byte1: x x x n1 n2 n3 n4 n5
Byte2: x n6 n7 n8 n9 n10 n11 n12
assuming n1 is the high order bit, you'd just say
value = ((ord(byte1) & 0x1f) << 7) | (ord(byte2) & 0x3f)
or something like that.
