.astype("int") or .astype(int)? Any differences between with and without quote/double?

Question

I have a DataFrame and one of its column consist of float type objects. I want to convert to int. As I tried, both .astype("int") and astype(int) methods work. I just wonder whether there is/are any difference(s)?

Answer 1

AFAIK there is no major difference...

.astype(dtype) should accept everything what is accepted by numpy.dtype().

Internally it does this:

dtype = np.dtype(dtype)
