In Python we can initialise an array with [[]]. But how to initialise a Numpy array without using numpy.zeros, numpy.ones & numpy.empty ? I don't want to use these functions because it fills in my Numpy array.

  • note that numpy arrays are not dynamically growing arrays. So in most cases initializing a completely empty array makes no sense. Commented Feb 24, 2015 at 13:36
  • numpy.empty doesn't fill your array, it just allocates some memory space of appropriate size and keeps that memory "as is". Commented Feb 24, 2015 at 13:42

All the lack of sense in your question aside (Numpy arrays are statically sized on creation), 

numpy.ndarray((dim1,dim2,...))

will create a dim1 x dim2 (x dimN) array and skip initialization.
