My understanding is that void is used before a method that will not return a result. But it's also used in front of methods that are doing a calculation, and definitely returning a result. Where am i misunderstanding this?

So lambda functions are mostly used for doing simple things (like additions) without having to define a new function "add_numbers"? Also taking into account that i wont repeatedly use the same lambda function.

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?

I am coming from a decent C++ background, C++ has issues of datatype handling but I see python has dynamic data type management policies (didn't know what to call them), in doing so is there any memory complexity?
