Which library is commonly used in Python Turtle programming for drawing graphics?

The library commonly used in Python for drawing graphics is the "turtle" library. Here are the steps to use it:

1. Import the turtle module: First, you need to import the turtle module using the command import turtle.

2. Create a new turtle screen: After importing the turtle module, create a new turtle screen using the command wn = turtle.Screen().

3. Create a new turtle object: Now, create a new turtle object using the command t = turtle.Turtle().

4. Use turtle commands to draw graphics: You can now use various turtle commands to draw graphics. For example, t.forward(100) will move the turtle forward by 100 units, t.right(90) will turn the turtle 90 degrees to the right, etc.

5. Close the turtle screen: Once you're done drawing, you can close the turtle screen using the command turtle.done().

Remember, the turtle library is a built-in library in Python, so you don't need to install it separately.
