In this module, you will: Import the NumPy Python library into your VS Code Jupyter Notebook Learn how NumPy arrays compare to Python lists Learn how to use NumPy arrays for large in-memory datasets Explore NumPy functions for arrays and simple data manipulation ...
# Import numpy import numpy as np # Create a numpy array from height_in: np_height_in np_height_in=np.array(height_in) # Print out np_height_in print(np_height_in) # Convert np_height_in to m: np_height_m np_height_m=np_height_in*0.0254 # Print np_heigh...
NumPy operations perform complex computations on entire arrays without the need for Python for loops. e.g. Conclusion NumPy-based algorithms are generally 10 to 100 times faster (or more) than their pure Python counterparts and use significantly less memory. ...
