Also, opening-and-not-closing a set of brackets is almost the only
way in Python to make this kind of error (syntax at one line, actual
mistake far before).

See if your editor has a show-the-matching-bracket mode.

I use vi/vim and it both shows the matching bracket when the cursor
is on one and also have a keystroke to bounce the curser between
this bracket and the matching one.

If you suspect you failed to close a bracket, one approach is to
go _below_ the syntax error (or right on it) and type a closing
bracket. Then see where the editor thinks the opening one is.

If you have a syntax highlighting editor (highlights keywords,
colours quoted text differently, etc) it can also be useful for
finding errors; the text will be the wrong colour at some point.

Just a few suggestions to aid finding this kind of thing without
outside help.
