The standard way to bin a large array to a smaller one by averaging is to reshape it into a higher dimension and then take the means over the appropriate new axes. The following function does this, assuming that each dimension of the new shape is a factor of the corresponding dimension in the old one.

  • A "for" loop is probably the easiest loop to use in Python for the mean of a list. Set a variable equal to zero and iterate over each element of the list, adding its value to the new variable. When the loop is done, compute the length of the list using Python's built-in "len" function. Divide the sum by …

  • Python’s numpy module provides a function to find the unique elements in a numpy array i.e. Python numpy.unique(ar, return_index=False, return_inverse=False, return_counts=False, axis=None)
  • An array of weights associated with the values in a. Each value in a contributes to the average according to its associated weight. The weights array can either be 1-D (in which case its length must be the size of a along the given axis) or of the same shape as a .
