Random Arrays – NumPy

• Random Module in NumPy (numpy.random)
• Functions for generating random numbers from Random Module
• Generating random numbers:
  • np.random.rand(): random float from 0 to 1
  • np.random.randn():
  • random.rand(): Random floats: yes,
  • randn() ?? # returns a random float between 0 and 1.
  • np.random.randint(range): Random integers in a range
  • random.randint(100, size=(5)): Random Array:
    • random.randint(100, size=(3, 5)): Random Array:
  • np.random.normal():
• Random samples/sampling:
  • random.random_sample()
  • random.choice()
  • random.shuffle()
• np.random.seed(): Seeding for reproducibility/Setting seed
• Permutations and shuffling:
  • np.random.permutation():
  • np.random.shuffle():
• Probability distributions:
  • np.random.normal() – Normal distribution
  • np.random.uniform() – Uniform distribution
  • np.random.binomial() – Binomial distribution
