PEP 8: Byte Order Mark (BOM) vs coding cookie
PEP 8 says ... Files using ASCII (or UTF-8, for Python 3.0) should not have a coding cookie. What about a BOM (Byte Order Mark)? Per Wikipedia ... http://en.wikipedia.org/wiki/Byte-order_mark#endnote_UTF-8) 'In UTF-8, this is not really a "byte order" mark. It identifies the text as UTF-8 but doesn't say anything about the byte order, because UTF-8 does not have byte order issues.' So is it good style to omit the BOM in UTF-8 for Python 3.0? -- http://mail.python.org/mailman/listinfo/python-list
Re: recursively change values in list of lists
I see no recursion in the problem as stated. Can a polygon contain another polygon? I can see that if you had ... e_1 = [(0,0),(3,0)] e_2 = [(3,0),(2,3)] e_3 = [(2,3),(0,0)] triangle_1 = [e_1,e_2,e_3] w_1 = [triangle_1,] ... you might want to make a copy of triangle_1 that was offset by some amount and add it to w_1. Is that the idea? -- http://mail.python.org/mailman/listinfo/python-list
