The number.empty() function of the NumPy module creates an array of a specified size with the default value=” None”. Syntax: numpy.empty(size,dtype=object) Example: import numpy as np array = np.empty(5, dtype=object) print(array) The output of the above code will be as shown ...
here,empty()method of numpy is used to create a numpy array of given size with default value None. Below is the Python code given: 1 2 3 4 5 6 7 8 9 10 11 12 # import numpy module importnumpy # number of elements n=10 # array of n elements arr=numpy.empty(n,dtype=object) ...
