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.
