List of tuples
Summary
15. Summary – tuples

Instruction

All right, it's time to wrap things up! Let's have a quick summary of what we've learned before we move on:

  1. Tuples are frequently used to return multiple values from a function.
    2. def get_min_max(input_list):
  ...
  return (min, max)
  2. Tuples as function result types are often unpacked into multiple variables.
    3. list_min, list_max = get_min_max(user_list)
  3. Use underscores to ignore certain values.
    4. _, list_max = get_min_max(user_list)
  4. Tuples often represent real-world objects ...
    5. person = ('Mark', 28, 'Spanish')
  5. ... or certain states/positions.
    6. x_y_coordinates = (5, -14)
  6. Tuples are often used in conjunction with lists.
    7. people = [
  ('Mark', 28, 'Spanish'),
  ('Miranda', 21, 'ZEA')
]
  7. To compare two lists element by element, we can use the zip() function.
    8. for pair in zip(list_1, list_2):
  if pair[0] == pair[1]:
    ...
