Web# Initialize your variable as an empty list first In [32]: x=[] # and now cast it as a numpy ndarray In [33]: x=np.array(x) The result will be: In [34]: x Out[34]: array([], dtype=float64) Therefore you can directly initialize an np array as follows: In [36]: x= np.array([], dtype=np.float64) I hope this helps.

WebWe can create a NumPy array using a Python List. For example, import numpy as np. # create a list named list1 . list1 = [2, 4, 6, 8] # create numpy array using list1 . array1 = np.array(list1) print(array1) # Output: [2 4 6 8] Run Code. In the above example, we first imported the numpy library as np and created a list named list1.
