Convert NumPy array to Python list

Question

How do I convert a NumPy array into a Python List? Answer Use tolist(): Note that this converts the values from whatever numpy type they may have (e.g. np.int32 or np.float32) to the "nearest compatible Python type" (in a list). If you want to preserve the numpy data types, you could call list() on your array instead, and you'll end

Accepted Answer

Use tolist():>>> import numpy as np>>> np.array([[1,2,3],[4,5,6]]).tolist()[[1, 2, 3], [4, 5, 6]]Note that this converts the values from whatever numpy type they may have (e.g. np.int32 or np.float32) to the &#8220;nearest compatible Python type&#8221; (in a list). If you want to preserve the numpy data types, you could call list() on your array instead, and you&#8217;ll end up with a list of numpy scalars. (Thanks to Mr_and_Mrs_D for pointing that out in a comment.)
