basics of programming in Python
fundamental concepts of programming
solve human problems using Python
Useful studying tips from Prof:
1. Rubber duck technique-explain your program to a rubber duck verbally
(helps you figure out solutions to problems)
2. Familiarize yourself with the course site
Inverted/Flipped Classroom
Prepare-view lecture videos and finish the exercises (Due Sundays by 10 pm online)
Rehearse-apply concepts from videos (completed in lecture)
Perform-demonstrate understanding by completing exercise (Due Friday by 6pm online)
Use PCRS-Programming Course Resource System for Prepare and Perform
use UTORID and password to log in
Assignments due on Tuesdays before 10:00 pm
submitting partially finished work results in partial marks
Midterm tests are during lecture times

Getting Help
Piazza (online discussion forum) post questions and answer questions.
Don’t post code until after assignments are due
Email instructors and TAs with questions
Use the drop in centre or help centres
To do list for first week:
Read Syllabus
Bookmark course website
Check Blackboard (Portal) for announcements

Types
different kinds of information in Python are called types
every value has a type, which determines behaviour of values
two kinds are called floats and integers
Floats
short for floating point number
the floating point refers to the decimal
one slash “ / “ is used for floating point division, which produces a float result
e.g 10/3 = 3.33333333335 ->a close but inexact answer
Integers
numbers with no decimal points
use two slashes “ // “ for integer division, which produces an integer result
e.g: typing 9//3 will produce an integer result of 3
the results are not rounded but truncated
e.g 7/4 = 1.75 but 7//4 = 1
How to write comments
Use a number sign “#” to write comments in Wing IDE 101
everything that follows will not be executed by the program
Modulo Division
use a percentage sign “ % “ for modulo division, which returns a remainder
e.g 10 % 3 = 1
15 % 4 = 3
8 % 2 =0
5 % 2 = 1
5 % 3 = 2
Order of Precedence (from highest to lowest) :
Exponentiation (**)
Negation(-)
multiplication, integer, float, mod division ( * , / , // , %)
Work left to right
addition and subtraction ( + , - )
Use parentheses to override this, and to make equations clearer
Syntax Errors
typing 2 ** 2, 2 ** 2 both will produce the correct result
typing 2 * * 2 will produce a syntax error
Python assumes that anything directly following a * should be a value, unless it’s **
which means exponentiation
other syntax errors include:
3 + -> unfinished expressions
4 + 5 ) -> extra parenthese
5 / 0 -> divide by 0 error
