Import numpy as np

Write a NumPy program to print the NumPy version in your system. Sample Solution:- Python Code: import numpy as np print(np.__version__) Sample Output: 1.12.0 2020-05-02 import numpy as np It keeps your code more readable, when you see a call like np.sum(array) you are reminded that you should work with an numpy array. The second reason is that many of the numpy functions have identical names as functions in other modules like scipy If you use both its always clear which one you are using.
