The main use of NumPy empty is that it enables you to quickly create an array with a specific size and shape. So if you need a “holding container” for some future values, you can use the NumPy empty function to create it. In this sense, it’s very similar tothe NumPy ones functio...
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 ...

my_string = np.array_str(my_array) print(f"My string converted from array: {my_string}") print(type(my_string)) You can see that the data result is the same and the type changed from ndarray to string as well. See alsoHow to create empty array in Numpy?
