Interesting. But that bug potentially exists regardless of what PEP8 says.
Yes, but if you encourage people to spell it the first way, you can't accidentally leave part of your expression out of your result. However, I wouldn't write it like *either* of those. To me, the options are: result = expr1 + expr2 and result = expr1 + expr 2 And either of those would give an immediate IndentationError without the parentheses. So indenting the continuation is even better than choosing where to place the binary operator. ChrisA
