• What is the purpose of using underscores in function, method, and parameter names in
Blender Python scripting?
• Answer:
• Underscores in function, method, and parameter names are used to separate words,
making the names more readable and easier to understand. This practice follows the
naming conventions in Python, improving code clarity.
• Question:
• How do dots in the code facilitate access to different parts of the Blender Python API?
• Answer:
• Dots in the code allow you to navigate through the Blender Python API by accessing
different modules, classes, and functions. This structure helps organize and manage the
code efficiently, making it easier to find and use specific functionalities.

• What is a cylinder in 3D design, and how can the number of vertices affect its
appearance?
• Answer:
• A cylinder is a 3D shape with circular faces on both ends and straight sides.
• Increasing the number of vertices around the circumference makes the cylinder appear
smoother.

Teacher Name: Hala Nizar SH
