Task 12 time difference problem with brackets

Please sorry for delay, I didn't at once understand the question.

I see now you have problem solved already by using something like

print('('+str(d3),str(h3),str(m3),str(s3)+') ')

That's very good!

I can only add that sometimes the string template can be used in such cases:

result = "(%s %s %s %s)" % (d3, h3, m3, s3)

You see, we form template just as we want result string to look like - but put %s in places where values should be. Then we pass values in a tuple, after % operator. If there is only one value, it can be passed without tuple.
