How do I use Python Turtle to manipulate X and Y coordinates?

The Python Turtle library provides several methods to manipulate the X and Y coordinates of the turtle. Here's how you can do it:

1. Moving to Specific Coordinates Using `goto(x, y)`:

- The `goto(x, y)` method directly moves the turtle to the specified X and Y coordinates. The origin (0, 0) is at the center of the screen. Positive X moves the turtle to the right, negative X moves it to the left. Positive Y moves it up, and negative Y moves it down.

- Example:

import turtle

screen = turtle.Screen()
screen.setup(width=600, height=600) # Set up screen size (optional)
turtle_instance = turtle.Turtle()

# Move to (100, 100)
turtle_instance.goto(100, 100)

# Move to (-50, -50)
turtle_instance.goto(-50, -50)

screen.mainloop() # Keep the window open

2. Getting Current Coordinates Using `position()` or `pos()`:

- The `position()` or `pos()` methods return the current (x, y) coordinates of the turtle as a tuple. You can use this to find where the turtle is currently located before moving it further.

- Example:

import turtle

screen = turtle.Screen()
screen.setup(width=600, height=600) # Set up screen size (optional)
turtle_instance = turtle.Turtle()

turtle_instance.forward(50) # Move forward
current_position = turtle_instance.pos()
print(f"Current position: {current_position}")

turtle_instance.goto(0,0) # Go back to the origin
new_position = turtle_instance.position()
print(f"New position: {new_position}")

screen.mainloop() # Keep the window open

3. Setting X and Y Coordinates Directly with `setx(x)` and `sety(y)`:

- `setx(x)` moves the turtle to the specified x-coordinate, maintaining its current y-coordinate. Similarly, `sety(y)` moves the turtle to the specified y-coordinate, keeping its current x-coordinate unchanged.

- Example:

import turtle

screen = turtle.Screen()
screen.setup(width=600, height=600) # Set up screen size (optional)
turtle_instance = turtle.Turtle()

turtle_instance.forward(50)
turtle_instance.setx(100) # Move to x=100, keep the same y
print(f"Current position after setx(): {turtle_instance.pos()}")
turtle_instance.sety(-50) # Move to y=-50, keep the same x
print(f"Current position after sety(): {turtle_instance.pos()}")

screen.mainloop() # Keep the window open

4. Relative Movements with `forward(distance)`, `backward(distance)`, and `move()` :

- Though not directly manipulating x and y, these functions alter the turtle's coordinates based on its current heading (direction the turtle is facing). Forward and backward moves are relative to the heading and therefore change the x and y coordinates in relation.

By combining these methods, you can create intricate patterns and drawings using Python Turtle. Remember that understanding the coordinate system (positive and negative values, origin at the center) is key to accurate manipulation.
