I find myself doing this more and more often. It can also help to make
the code more readable and the intention more clear. Here's one example:
return (getTerminalFromProcess()
or getTerminalFromDirectory('/usr/bin')
or getTerminalFromDirectory('/bin')
or getCommonTerminal(('konsole', 'xterm'))
)
It's easier to read than using a "\" at the end of lines, writing it all
on one line would make for an unreadably long line, while building up
the final result in steps would make the logic less clear.

I found myself building a complicated logical condition with many ands and ors
which I made more manageable by putting the various terms on individual lines
and breaking them with the "\" line continuation character. In this context it
would have been nice to be able to add comments to lines terms which of course
isn't possible because the backslash must be the last character on the line.
Question: If the Python syntax were changed to allow comments after line-ending
backslashes, would it break any existing code? I can't think of an example.
Well you can if you use parenthesis like in:
x = 5
a = (x > 3 and
# x < 21 or
x > 100
)
You don't need the "\" to continue a line in this case
