First, you need to know what the formula for pi actually is. You can find
that by googling, or look it up in a maths book. You should expect
something like
pi = sum from i=0 to infinity of 4 divided by (something)
Then you want a program to print a table that looks something like this:
i value
0 xxxxx
1 xxxxx
2 xxxxx
etc., where the "xxxxx" will get filled in later, and the table stops at
a certain maximum value of i. Here is a hint:
for i in range(100):
x = "calculate something"
print("%d %s" % (i, x)
Does that get you started? Try writing some code and see how far you get.
Good luck!

Then you better get started straight away then. Turn off Facebook and
Twitter and do some real work.
