I was looking at the codetype object, and in particular the co_flags attribute. I wrote a tiny function def f(a,b,c,*args): print a,b,c,args Which was compiled to a codetype object. examining the codetype object, the container (the outer codetype) co_flag is set to 64, the function (the inner codetype) is 71 According to the docs 0x40 (64) is set if the function has variable args (eg *args) and that bit is set on the outer and inner codetype objects. I'm just wondering why the container is set to 64 as all it does is set functions up eg there is no variable arguments used? what the other bits in the function codetype co_flags do? Is there a comprehensive list of the various flags as the documentation alludes to 'reserved for internal use' but nothing else is mentioned? I'm using python 2.7.10 Continue reading...
