Programming Problem 21

Write a Python function that does the following:

  1. Its name is zip_lists
  2. It takes three arguments: list_1, list_2, list_3 – all of the same length
  3. It iterates over all three lists (remember, they have the same length, so you can use the same index for all of them) appending to a new list of tuples of three elements
  4. It returns the list of tuples

Test cases:

print( zip_lists([1, 2], ["a", "b"], [1.0, 2.0]) ) # [(1, "a", 1.0), (2, "b", 2.0)]
print( zip_lists([], [], []) ) # []

Name the program create_tuples.py. Make sure that gradescope gives you the points for passing the test case.

Programming Problem 22

Due date: Wednesday, November 04, 2026 at 9pm

Write a Python function that does the following:

  1. Its name is all_mappings
  2. It takes a single dictionary as an argument, which maps strings to lists of integers
  3. It returns a list of 2-value tuples, where the first value of the tuples is a key from D, and the second value is an element from its associated list value

Test cases:

print( all_mappings({"a": [7, 3, 1]}) ) # [("a", 7), ("a", 3), ("a", 1)]
print( all_mappings({"a": [8], "b": [2]}) ) # [("a", 8), ("b", 2)]
print( all_mappings({"a": [], "b": [2]}) ) # [("b", 2)]
print( all_mappings({}) ) # []

Name the program mappings.py. Make sure that gradescope gives you the points for passing the test case.
