Grouping shapes in PowerPoint can greatly simplify the shape editing process, especially when dealing with complex arrangements of shapes. It allows you to modify the entire group collectively, saving time and effort compared to adjusting each shape individually. This is particularly beneficial when you need to apply consistent formatting or positioning to a set of shapes. Ungrouping shapes provides increased flexibility and customization options. By ungrouping a set of grouped shapes, you regain individual control over each shape. This allows you to make specific modifications, resize or reposition individual shapes, and apply unique formatting or styling as needed. In this article, we will explain how to group and ungroup shapes in PowerPoint in Python using Spire.Presentation for Python.
