Write a python program?

Question

Write a python program that finds the value of pi to 20 decimal places. 

 

Please provide me the shortest code as possible. Thanks.

Answer 1

are you allowed to actually type in the first 20 dec places, which are well-established, and then println?  This would be the easiest

 

alternatively, you can use converging series http://mathworld.wolfram.com/PiFormulas.html
