📄 Python cheat sheet

Python reads your code from top to bottom. Lines inside a loop, if, or def must be indented 4 spaces. Lines that start with for, while, if, elif, else, or def end with a colon :

Moving

`move_forward()`	Move one square the way you face. `move_forward(3)` moves 3.	⬆️ Move forward
`turn_left()` `turn_right()`	Turn to face a new way. You stay on the same square.	↺ ↻ Turn
`move_right()` and friends	Move right, left, up, or down no matter which way you face. Used in Show Python for arrow blocks.	➡️ ⬅️ ⬆️ ⬇️

Loops

for i in range(4): move_forward()	Repeats the indented lines 4 times.	🔁 Repeat 4 times
while not at_flag(): move_forward()	Keeps repeating until the Champion reaches the flag.	🔁 Repeat until 🚩

Checks and decisions

if path_ahead(): move_forward() elif path_left(): turn_left() else: turn_right()	Checks the path. Runs the first part that is True. else runs when nothing above was True.	❓ If / Else
`path_ahead()` `path_left()` `path_right()` `at_flag()`	Checks that answer True or False. Use them with if or while.

Variables and math

steps = 1 steps = steps + 1 steps += 1 steps -= 1	A variable is a named box for a number. `+=` adds to it, `-=` takes away.	📦 steps
`move_forward(steps)`	Moves forward as many squares as the variable holds.
`print("Hi!")` `print(steps)`	Shows a message or a value in the output box.

Functions

def hop():
    turn_left()
    move_forward()

hop()

def makes a function. Its lines run only when you call it with hop(). Put the def above the code that uses it.

🧩 Function

📏 Angle guide

When your Champion walks all the way around a shape and ends up facing the way it started, it has turned one full circle: 360°. So for a shape with corners that are all the same:

turn angle = 360 ÷ number of corners

Turn angle vs. inside angle

The Champion turns at the outside of each corner. A triangle’s inside corner is 60°, but the Champion turns 120°, because 180 − 60 = 120. Turn angle = 180 − inside angle.

Common turns

Tip: press 📐 Protractor to see angle marks around your Champion. Blue numbers are right turns, orange numbers are left turns.
