Hướng dẫn dùng numpy sum python

numpy.sum[arr, axis, dtype, out] : This function returns the sum of array elements over the specified axis.

Parameters : 
arr : input array. 
axis : axis along which we want to calculate the sum value. Otherwise, it will consider arr to be flattened[works on all the axis]. axis = 0 means along the column and axis = 1 means working along the row. 
out : Different array in which we want to place the result. The array must have same dimensions as expected output. Default is None. 
initial : [scalar, optional] Starting value of the sum. 
Return : Sum of the array elements [a scalar value if axis is none] or array with sum values along the specified axis.
