KC Knowledge Check

The Knowledge Check is intended to support learning and self-assessment. The questions highlight the key concepts of this unit and help prepare for the final examination.

The Knowledge Check is not graded.

1️⃣ Theory

Briefly explain the difference between:

  • a list
  • a NumPy array

2️⃣ Working with Lists

Assume:

my_list = [4, 7, 1, 9]

Write Python statements that:

  • print the second element,
  • print the length of the list,
  • append the value 5 to the end of the list.

3️⃣ List and Conditional Statement

Assume:

numbers = [12, 8, 22, 5]

Write Python statements that:

  • replace the value 8 with 10,
  • remove the value 22 from the list,
  • print the modified list.

4️⃣ Working with Arrays

Assume:

import numpy as np

a = np.array([3, 8, 5])
b = np.array([4, 7, 6])

Write a Python program that compares the first element of both arrays and prints the larger value.

5️⃣ Lists and Conditions

Assume:

colors = ["red", "green", "blue"]

Write a Python program that:

  • checks whether the list contains three elements,
  • prints "List complete" if the condition is true,
  • otherwise prints "List incomplete".

Discussion

The solutions will be discussed during the course session.
