following in gmane.comp.python.general:

> I'm so lost. Given the formula pi=4-4/3+4/5-4/7+4/9-4/11+...... How do I print a table showing approximate value of pi by computing one term4-4/3 then two terms4-4/3+4/5, and so on.Then how many terms of the series before I get 3.14, 3.141, 3.1415, 3.14159. Please helps computer teacher literally says figure it out and doesn't help and expects a perfect program.this is in python 3 please give an answer I can understand and an example.

	It is homework... No one will give you an answer... Normally we'd
ask you to show use what you have tried, and we'd try to suggest where
you went wrong. I'll give you five hints...

	HINT: The first term of the equation is equivalent to 4/1
	HINT: The denominators are odd integers.
	HINT: Each iteration is adding 4/<nextodd> to the preceding sum
	HINT: Subtraction is the addition of a negative value
	HINT: Each "even" term is a subtraction
