Worksheet: Chapter 4

Part 1: The Mining Drill (Tracing)

Be the computer! Look at the loop code and write exactly what it will print in the box.

                    for i in range(3):

                      print("Dig")

                    energy = 2

                    while energy > 0:

                      print(energy)

                      energy = energy - 1

Part 2: How High Does It Go?

If you type range(5), which numbers does the computer count? Circle the correct numbers.

0

1

2

3

4

5

6

(Hint: Computers start counting at Zero!)

Part 3: Infinite Danger

One of these loops is broken and will run forever (crash!). Circle the Safe Loop and put an X on the Infinite Loop.

timer = 10
while timer > 0:
print("Running...")

(Missing math!)

timer = 10
while timer > 0:
print("Running...")
timer = timer - 1

(Subtracts timer)

Part 4: The AFK Farmer

Write a Python script that repeats "XP Gained!" exactly 4 times.

# Create a loop for 4 times
for i in range():
(Don't forget to indent!)
print("")
