Numpy: repeat cells variable number of times

[paul18fr]

Hi

In the following snippet, each cell of CellsToDuplicateVariableTimes is repeated the number of times defined in NumberOfReplicationPerCell : i'm sure there's a more relevant way to proceed => how would you do?

Thanks

Paul

CellsToDuplicateVariableTimes = np.array([2, 6, 8, 10, 11])
NumberOfReplicationPerCell = np.array([4, 3, 2, 5, 1])

New = np.zeros(0, dtype = int)
n = np.shape(CellsToDuplicateVariableTimes)[0]
List = [np.repeat(CellsToDuplicateVariableTimes[i], NumberOfReplicationPerCell[i]) for i in range(n)]
for arr in List: New = np.hstack((New, arr))

print(f"New = {New}")

Output:
New = [ 2  2  2  2  6  6  6  8  8 10 10 10 10 10 11]
