Re: [Tutor] hypotenuse

assert 4**0.5 == 2 More generally: nth root of x: x ** (1.0/n) Or even more generally, take the 3rd root of the square of x: x ** (2.0/3.0) And when we are already extending the scope of the mailing list to math basics: 1.0/(x**2) == x**-2 (negating the power gives the inverse.) Andreas Am

[Tutor] hypotenuse

I am in an early lesson in "A Byte of Python." Instead of writing a program to find the area of a rectangle I thought it would be useful to write a program to determine the length of the diagonal of a "golden rectangle", which would of course equal the sq root of the sum of the squares of the widt

It appears to me that the following line would not work: >Circle = Oval(points) The variable "points" is a list of six points, and I don't know how one would define a circle or oval with 6 points. At the top part of your program, an oval is defined using two points, which makes sense. Maybe

[Tutor] Hello

Hi, I'm in a Python class and we were given the assignment to create our own graphic and my idea was to have a program that asks the user to click six points and then create a circle using the six points they clicked. Once they've done that I want eyes and a mouth to appear in the circle. I was

Hi Meftah. Under the 'beginner programming' section of Python we have a lot of free video examples of Python coding: http://showmedo.com/videos/python?topic=beginner_programming and if you look under 'all' for Python: http://showmedo.com/videos/python?topic=all you'll find IDE videos on PyDev, SP

Re: [Tutor] Simple reg-ex syntax?

How I would improve this: compile the regular expression. This is more efficient. self.digit_extractor = re.compile('(\d+)') then, use the findall method: self.allNumbers = self.digit_extractor.findall(self.aString) which will even work with multiline strings, but doesn't convert to integers.
