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 the above code seems from an experienced author. The curious thing to me is the variable 'sz'. I have check np.zeros(shape, ..) shape : int or sequence of ints The introduced 'sz' is a tuple. If n_iter function is similar to a constant in C, I don't see the reason for 'sz'. In fact, 'n_iter' is an int, which fits the below np.zeros(shape) correctly. Could you see something useful with variable 'sz'? Thanks, -- https://mail.python.org/mailman/listinfo/python-list
