Why on earth would you want to return the square root of a number as an integer? For example, take the square root of 8. It's something like 2.8284271....
But if you must know, the function is simply int(). However, that will just rip off whatever decimal part the number has. So int(4.99999) would return 4. If you want to round to the nearest integer, use the round() function. BTW, the F1 key is your best friend.
