Is there any reason to introduce this intermediate variable (sz)?

Hi, I find the following code snippet, which is useful in my project: n_iter = 50 sz = (n_iter,) # size of array x = -0.37727 z = np.random.normal(x,0.1,size=sz) Q = 1e-5 # process variance # allocate space for arrays xhat=np.zeros(sz) P=np.zeros(sz) I learn Python now and

Re: Is there any reason to introduce this intermediate variable (sz)?

In fl writes: > I still don't see the necessity of 'sz'. Thanks, sz isn't required. You can use (n_iter,) in place of sz. However, as I posted earlier, sz is shorter so it might make your code easier to read. Using
