This will print "is".

Here's the step by step explanation:

1. In Python, strings are indexed with the first character having index 0. Negative indexing starts from the end of the string.

2. The string "Python is cool" is indexed as follows:

P(0) y(1) t(2) h(3) o(4) n(5) (6) i(7) s(8) (9) c(10) o(11) o(12) l(13)

3. a[7:-5] means start at index 7 and end at 5 places from the end (or -5 when counted from the end).

4. So, it starts at 'i' (index 7) and ends at ' ' (space after 'is', which is index -5 when counted from the end).

5. Therefore, it prints "is".
