Hi all!
I sometimes put (per a hint I found on a web search) code like that at the
beginning of my Python programs:
if sys.version_info > (3,):
long = int
xrange = range
(e.g:
https://github.com/shlomif/project-euler/blob/master/project-euler/581/euler_581_v3.py#L4
)
This is a py2/py3 compatibility shim.
My question is whether I should put it only at the main program's file or also
at each and every *.py module that I load? I'm not sure I understand the python
handling of symbols well enough to answer that.
Thanks and happy holidays!
