Q&A Discussions
I'm trying to calculate the decimal places of pi with Ramanujan's formula. but with this code I'm getting the same output for all values of n, which it shouldn't.
from math import sqrt, factorial as f
sum=0
n=0
k=(2*sqrt(2)/9801)
while n<=100000:
sum=sum+((f(4*n))*(1103+(26390*n)))/(((f(n))**4)*(396**(4*n)))
y=1/(k*sum)
print('%.60f' % y)
n=n+1
where am I doing wrong?

public static void main (string[ ] args)

static?
void?
main is a method which creates a string array named args. why the name args?

can someone kindly correct me if i am wrong about this quote "As the program contains multiple lines of code, you should create it as a separate file and run it."
does that mean that if my code gets bigger it is advisable to create less line of codes but many files?

nums = [i**2 for i in range(5)]
print(nums)
[1, 4, 9, 16]
"..what will this create..?"
"Correct" answer was:
"A list of even numbers between 0 and 18."
9 is not an even number tho.
Is this a typo or am i missunderstanding/missinterpreting?

Isn't this just a reoccurring function called from within itself until a particular set of conditions are met? I don't know it just seems like shorthand to me. Like a do-while loop. I am sure it could be used for more than just factorials.
