[Tutor] Decimals 'not equal to themselves' (e.g. 0.2 equals 0.200000001)

I am very new to Python (I started learning it just yesterday), but I have encountered a problem. I want to make a simple script that calculates the n-th root of a given number (e.g. 4th root of 625--obviously five, but it's just an example :P), and because there is no nth-root function in
