🐾 The Endless Maze

PixelPup needs to walk through a series of steps over and over. Instead of typing each move again and again, we use a loop!

Loop is what we call in computer language for repeating the same task again and again. In this case, pixel pup has to move forward for 100 steps – so you do not want to type move forward a 100 times to reach your destination.

Here’s an example using a for loop:

steps = ["forward", "left", "forward", "right", "forward"]

for move in steps:
    print("PixelPup goes", move)

print("PixelPup found the glowing key! 🗝️")

In this example, PixelPup needs to follow five steps in the maze:

👉 Forward, Left, Forward, Right, Forward

When we run the code, it tells PixelPup what to do:

PixelPup goes forward
PixelPup goes left
PixelPup goes forward
PixelPup goes right
PixelPup goes forward

We use something called a loop to do this easily without typing the same thing again and again!

Here’s how it works:

• The for loop goes through each move in a list and tells PixelPup what to do.
• The special words you need are:
  for move in steps: — and it repeats for each word in your list!

You can also use a while loop, which keeps repeating something until a condition is true.

energy = 5

while energy > 0:
    print("PixelPup moves one step in the maze")
    energy -= 1

print("PixelPup is out of energy! Time to recharge! ⚡")

So the above code will continue pushing the pixel up one step until the variable energy is zero.

Also note that we are reducing energy by 1 – but that is an arithemetic operation for a future episode!

Loops help PixelPup save time and stay efficient — just like real coders!
