I have a question about best practices when it comes to line wrapping/
continuation and indentation, specifically in the case of an if
statement.
When I write an if statement with many conditions, I prefer to use a
parenthesis around the whole block and get the implicit continuation,
rather than ending each line with an escape character. Thus, using
the example from the style guide (http://www.python.org/dev/peps/
pep-0008/) I would write:
if (width == 0 and
height == 0 and
color == 'red' and
emphasis == 'strong' or
highlight > 100):
raise ValueError("sorry, you lose")
The problem should be obvious -- it's not easy to see where the
conditional ends and the statement begins since they have the same
indentation. Part of the problem, I suppose, is that Emacs indents
'height' and the other lines in the conditional to 4 spaces (because
of the parenthesis). How do people deal with this situation?
I would probably use half-indentation:
if (width == 0 and
height == 0 and
color == 'red' and
emphasis == 'strong' or
highlight > 100):
raise ValueError("sorry, you lose")
Try doing that with tabs! :-)
if (width ==0 and
' \\ // ' and height == 0 and
' \\// ' and color == 'red' and
' /OO\ ' and emphasis == 'strong' and
' \></ ' or highlight > 100):
raise ValueError("sorry, you lose")
Try doing this with spaces !! :p
