    Study Notes

    Course Unification

    • The unification process aims to provide a consistent learning experience for all students, regardless of their section
    • Course unification included revisions to academic integrity and code of conduct guidelines
    • Generative AI tools are explicitly prohibited for assignments, but can be used for self-learning
    • The number of quizzes, assignments, and exams are unified across all sections

    Course Material

    • All course materials are available on Brightspace including:
      • Course syllabus
      • Announcements
      • Lecture slides (uploaded before class)
      • Solved exercises (uploaded after class)
      • Homework assignments
      • Grades

    Textbook

    Graded Activities

    • Class participation: 5%
      • Includes interaction and exercises
    • Random Quizzes: 10%
      • Six pop quizzes are evenly distributed throughout the semester
    • Assignments: 15%
      • Three total assignments
    • Final Project: 15%
      • Group project lasting two to three weeks
    • Mid-term Exam: 25%
      • Held during the last lecture before break
    • Final Exam: 30%

    Python type()

    • The built-in type() function returns the data type of a value or variable

    Python id()

    • The built-in id() function returns the memory location of a variable

    Data Types

    • type(3) returns int (integer)
    • type(4.5) returns float (floating point number)
    • type('abc') returns str (string)
    • type('1') returns str (string)
    • type(True) returns bool (boolean)
    • type(None) returns NoneType (None)

    Variable Assignments/Re-assignments

    • The data type of a variable can change based on the assignment
    • The data type is determined at runtime

    Python Input

    • The input() function returns a string value.
    • To use the input as a numerical value, use type casting:
      • int() for integers
      • float() for floating point numbers

    Characters

    • Characters are represented by their ASCII numerical codes

    ASCII Table

    • Every letter, digit, and symbol has a corresponding ASCII number

    ASCII-Character Conversion

    • ord(character) converts a character to its ASCII numerical value
    • chr(number) converts an ASCII numerical value to a character

    Recap on Strings

    • Strings are sequences of characters
    • Strings are defined using single or double quotes (' ', " ")

    String Indexing

    • Individual characters can be accessed by their index using square brackets []
    • Index starts from 0

    Lists

    • Lists are created using square brackets []
    • Lists are mutable, meaning they can be changed after creation
    • List items are indexed from 0
    • List slicing returns a new list

    Removing an Item from a List

    • list.remove(item) removes the first occurrence of the provided item
    • del list[index] removes the item at the specified index
    • list.pop() removes and returns the last item
    • list.pop(index) removes and returns the item at the specified index

    List Methods and Functions

    • .sort(): sorts items in ascending order
    • .reverse(): reverses the order of items
    • .count(item): counts the occurrences of an item
    • min(myList): returns the minimum value in the list
    • max(myList): returns the maximum value in the list

    Decision Structures

    • Program logic can branch based on conditions
    • Conditions evaluate to either True or False

    Logical Operators

    • Logical operators combine conditions
      • and: both conditions must be True
      • or: at least one condition must be True
      • not: negates a condition

    Loops

    • Loops allow code to be executed repeatedly
      • for loop: iterates through a sequence
        • while loop: executes as long as a condition is True

    String Methods

    • .replace(old, new, max): replaces old substring with new
    • .find(substring, start, end): finds first occurrence
    • .count(substring, start, end): counts occurrences
