Key Points

• Import a library into a program using import libraryname.
• Use the numpy library to work with arrays in Python.
• Use array[x, y] to select a single element from a 2D array.
• Array indices start at 0, not 1.
• Use low:high to specify a slice that includes the indices from low to high-1.
• Use the pyplot module from the matplotlib library for creating simple visualizations.
