I just noticed that in your code you used pop(0). It's not efficient
to pop an element off the front of a list because after doing so,
every other element in the list has to be moved over to the left one
position. If you pop() an element off the end of the list, then the
first element in the list

hello,
i have designed a desktop search utility in python and a file system

Maybe he meant

anybody would ever take the square of an angle.
What's the square root of pi/4 radians?
