python: converting an numpy array data type from int64 to int

numpy.ndarray.tolist will do it:

a.tolist()

If your data is a pandas series you can call their tolist wrapper with the same result.


@J.F. Sebastian's answer:

a.astype(numpy.int32)

Use the item() method for numpy.int64 object, as Mike T's answer in another similar question explained.
