add the complete code (python)

Create a function that computes the approximation of pi, based on the number of iterations specified. pi can be computed by 4*(1-1/3+1/5-1/7+1/9- ...). Examples >>> piApprox (1) 4.0 >>> piApprox (10) 3.04183961893 >>> piApprox (300) 3.13825932952 10 pt 1 def piApprox (num): 2 i = 1 3 pi = 0 while i : # set 'while' termination condition 00 OU AWNA pi += i+=1 return pi # compute the ith term of the series # update i 8
