Course Overview

Start Of Your Journey

• This class goes faster than 105
• Better matches the pace of the rest of the degree
• There will be a lot of work
• But if you can keep up you will be setup to succeed

Hands On Class

• This class demands participation
• You must show up to lecture and lab regularly to keep up
• Almost every class we will have a quiz
• Make sure to bring your computer or phone in order to complete the quizzes
• We will also have some paper quizzes and exams

Prerequisites

• This class expects you to have already programmed in any language
• If you took 105 then you have seen Python
• If not that is okay but you should still be familiar with the following:
  • Comments
  • Variables
  • If statements
  • Loops

Prerequisites Quiz

• We will be having 2 prerequisite quizzes
• 1 today and 1 on Friday
• These will count as normal quizzes
• These are designed to allow us (and you) to assess where you are at coming into this class
• If you get below a 70 average on these 2 quizzes you will need to quickly catch up not to fall behind
• If you get below a 50 average then you need to do a lot of work now to catchup

Python As Pseudocode

• To start the class we will review these prerequisite topics
• We will use Python to do this as most of you already know it
• If you don’t know you should be able to learn it very quickly

Comments

• Comments are lines of code which are only used to communicate to programmers
• Comments do not effect the output of a program
• Can add more context to a program

# This is a comment
x = 5 # This is an inline comment

Variables

• Variables store information
• This can be numbers, string, lists and more
• Variables can have their values changed as the program runs

x = 5     # x is 5
y = 6 + 3 # y is 9
z = y * 2 # z is 18

If Statements

• Allows a program to take branching paths
• If the condition is true then takes the first branch
• Otherwise checks the other branch conditions until it finds one which is true
• Or gets the the else at the end of the chain
• Does not have to have an else branch

x = 5
if x > 5: # If x is greater than 5
    # Then do these statements
    print("Greater than 5")
elif x == 5: # Else if x is equal to 5
    # Then do these statements
    print("Equal to 5")
else:
    # Else do these statements
    print("Less than 5")

Looping

• Allows a program to repeat a sequence of statements many times
• While loops repeat the body of the loop until the condition is false
• Loops can repeat as many times as they want

i = 0
while i < 5: # Loop until i is NOT less than 5
    # While the condition holds do these statements
    print(i)
    i = i + 1
    # Then check the condition again and repeat if necessary

Indentation

• In Python indentation matters
• Indentation is how many spaces/tabs precede a line of code
• In order for statements to be inside a given Python if statement or while loop they must be indented further than if/while
• For example:

x = 5
y = 6
if x < 5:
    x = 7 # This line is inside the if
y = 8 # This line is not
print(x) # Prints 5
print(y) # Prints 8

Indentation

x = 0
y = 0
while x < 10:
    x += 1   # This line is in the while loop
    print(x) # And so is this one
print(y) # But this is not
