This example line-continues via parentheses, so why isn't the right-paren enough?
My eyes are going; I no longer can see how many open parens are there without moving focus. The colon is a local indicator that allows me to avoid backtracking.
if (some() and some_other() or some_more(complex=(True,)) and a_final_call(egg=(1,2,3))): do_something()
This example uses the same mechanism as above.
Except that Python syntax allows you to omit one level of parentheses and still continue across lines, which you couldn't do without the colon. In this example I probably couldn't count the parentheses correctly even if I could see them all without moving eye focus. I love Lisp, but I'm also very glad that Python is not Lisp.
