The document discusses loops, lists, if/else logic, and user input in Python. It provides examples of for loops to iterate over lists and ranges, a while loop, and if/elif/else statements. User input is demonstrated by asking questions and storing the responses as variables. The document concludes by reminding students to continue working on projects and bring any questions to the next class, which will focus on making a simple game that pulls together concepts learned so far.

1. Loops and Logic

2. Loops
 For in List
for value in aliens:
sprite = codesters.Sprite(value, 0, -100)
 For in Range
for counter in range(10):
girl.say("Counter is " + str(counter))
 While
while counter < 5:
ufo.move_forward(100)
counter += 1

3. Lists
 aliens = ["alien1", "alien2", "purpleguy"]
 Square brackets on the outside
 Commas between items in list

4. Demo Time!
 Until 7:15

5. If/Elif/Else Logic
 if color == "blue":
knight.say("You are worthy, " + name + "! Continue
your quest to seek the " + quest + "!")
elif color == "green":
knight.hide()
sprite = codesters.Sprite("evilwizard", 0, -100)
else:
knight.say("Your mother was a hamster!")

6. User Input
 name = knight.ask("What is your name?")
 quest = knight.ask("What is your quest?")
 color = knight.ask("What is your favorite color?")
 color = color.lower() #force lower case for string
comparison
 Example: if color == "blue":
 String concatenation
 knight.say("You are worthy, " + name + "!”)
 Remember to add spaces before the variable if you need
them

7. Demo Time!
 Until 8:15

8. For Next Week
 Keep working on your projects!
 Try to finish all the lessons in Intro to Python Part 1
 Bring any questions or problems to the Library office
hours or to class next week
 Next week’s agenda: Pulling it all together to make a
simple game
 We will look over a few of the examples in Intro to
Python Part 2 and see how they work
 We will talk about random numbers as well
 Drawing lines with Sprites
