Please don't pass this misinformation along.

In the struct module document, see the section on the initial character:
     Character Byte order Size and alignment
       @          native            native
       =          native           standard
       <       little-endian       standard
       >        big-endian         standard
       !    network (= big-endian) standard
   and notes @ is the default.
