Fractal Tree
The provided code uses the turtle module in Python to draw a tree-like pattern on a graphics window. Here's a step-by-step explanation of how it works:
-
We define a base case that checks if depth is equal to 0.
- If the base case is hit, it means that the recursion has reached the desired depth, and the function simply returns, effectively stopping further recursion.
- If the base case is not met, the function continues to execute. The turtle moves forward by a distance of 20 * depth units. The depth parameter is used to control the length of each branch based on the depth level.
- The turtle then turns left by 30 degrees to change ...
