[issue21394] Lib/random.py: use more efficient code to convert bytes to integer

Do you mean int.from_bytes?

It's already changed in Python 3.5: int.from_bytes(_urandom(32), 'big').

[issue21394] Lib/random.py: use more efficient code to convert bytes to integer

[STINNER Victor]

New submission from STINNER Victor:

In Lib/random.py, I see lines like that:

   long(_hexlify(_urandom(32)), 16)

I guess that something more efficient can be fonud to convert a bytes string to 
an integer.

bytes.from_bytes() maybe?
