NumPy & Matplotlib

Week 4

NumPy

• NumPy: the absolute basics for beginners
• PDA 4: NumPy Basics: Arrays and Vectorized Computation
• Advent of Code 2015, Day 6 (hint: use a 1000x1000 2D array)

Matplotlib

• Matplotlib: tutorials
• The Python Graph Gallery

General Practice Problems

• Project Euler, Problem 37
• Project Euler, Problem 59
  • hint: ciphertext = np.loadtxt("https://projecteuler.net/project/resources/p059_cipher.txt", dtype=int, delimiter=',') will load the ciphertext into a NumPy array
  • hint: ord() converts a character to its integer ASCII code, chr() converts an integer ASCII code to a character
  • hint: the ^ operator performs XOR on two integers
• Project Euler, Problem 92

Also worth looking at: Seaborn

• Seaborn: statistical data visualization
