Return a new array of given shape and type, filled with zeros.
or
Return a new array of given shape and type, filled with ones.
or
Return a new array of given shape and type, without initializing entries.
However, the mentality in which we construct an array by appending elements to a list is not much used in numpy, because it’s less efficient (numpy datatypes are much closer to the underlying C arrays). Instead, you should preallocate the array to the size that you need it to be, and then fill in the rows. You can use numpy.append
if you must, though.
