[Python-Dev] Issue #21071: change struct.Struct.format type from bytes to str

Hi

I would like to change struct.Struct.format type from bytes to str. I
don't expect that anyone uses this attribute, and struct.Struct()
constructor accepts both bytes and str.

http://bugs.python.org/issue21071

It's just to be convenient: more functions accept str than bytes in
Python 3. Example: print() (python3 -bb raises an exceptions if you
pass bytes to print).

Is anything opposed to breaking the backward compatibility?

Victor
