Using empty() method of numpy module 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
print("2D-array: ", array_2d) In the above code: The “numpy.array()” is used to create the “1-D” and “2-D” array. The “print()” function accepts the numpy array as an argument and displays it on the console screen. ...
Python provides different functions to the users. To work with arrays, the Python library provides a numpy empty array function. It is used to create a new empty array as per user instruction means giving data type and shape of the array without initializing elements. An array plays a major...
empty(5, dtype=object) print(array) The output of the above code will be as shown below: [None None None None None] Direct Methods to initialize an array In the python language, we can directly initialize the elements inside an array using the below method. Syntax: array-name = [...
