 Python program to calculate π Chundnovsky's formulae: `\frac{426880\sqrt{10005}}{\pi}=` `\sum _{k=0}^{\infty}\frac{(6k)!(13591409+545140134k)}{(3k)!(k!)^3(-640320)^{3k}}` #made by Raxit Gupta import decimal  import math  #we use Chundnovsky's formulae def compute_pi(n):   decimal.getcontext().prec = n + 3   C = 426880 * decimal.Decimal(10005).sqrt()   K = decimal.Decimal(6)   M = decimal.Decimal(1)   X = decimal.Decimal(1)   L = decimal.Decimal(13591409)   S = L   # For better precision, we calculate to n+3 and remove the last two digit   for i in range(1, n+3):     M = decimal.Decimal(M* ((1728*i*i*i)-(2592*i*i)+(1104*i)-120)/(i*i*i))     L = decimal.Decimal(545140134+L)     X = decimal.Decimal(-262537412640768000*X)     S += decimal.Decimal((M*L) / X)     return str(C/S)[:-2] n=int(input("Enter decimal places:")) P=compute_pi(n) print(P)           if there is any mistake, please comment!
