Python Pandas merge only certain columns
...ge selected columns from two tables.
If table_1 contains t1_a,t1_b,t1_c..,id,..t1_z columns,
and table_2 contains t2_a, t2_b, t2_c..., id,..t2_z columns,
and only t1_a, id, t2_a are required in the final table, then

Jquery change background color
...n() {
var p = $("p#44.test").css("background-color", "yellow");
p.hide(1500).show(1500);
p.queue(function() {
p.css("background-color", "red");
});
});
});

Is there a builtin identity function in python?
...is none, a feature was asked in issue 1673203 And from Raymond Hettinger said there won't be:
Better to let people write their own trivial pass-throughs
and think about the signature and time costs.
So a better way to do it is actually (a lambda avoids naming the function):
