With the Python API we can customize Blender interface as we need. For example, we can place the most frequently used operators to the header (top menu) of any workspace area. This way we can assemble our own ribbon with “quick favorite” buttons.
When rendering animations in Blender, it’s often necessary to save one single frame for later use as a preview. Of course, we can do this manually, after finishing the animation rendering, switch to the desired frame and separately render it. However, with the Blender Python API, we can organize the automatic saving of the desired frame during the animation render.

To add a new strip to the Sequence Editor programmatically, we need to know the channel number to place it. We can get the number of an empty channel in the Sequence Editor throug the Blender Python API by walking through the list of sequences already added to the Sequence Editor.

Viewport Purge Button – Blender 3D add-on that adds the “Purge” button to 3D Viewport area header for clearing the scene from unused objects (meshes, materials, etc).
It doesn’t need to assemble a large and complex shader node tree to make a parallax shader in Blender. The simplest parallax effect can be achieved by connecting just 3 nodes.
Most video formats don’t have a built-in transparency channel, so the black and white mask – a separate video file that determines how one video will be blended on another, can be used for blending such videos.
The Blender Python API can be very useful not only for working with meshes or nodes but also when editing video files in the Video Sequence Editor.

The “face_strength” parameter is used in the Weighted Normal modifier to calculate normals. We can set and change its values by calling a special operator, or directly getting and setting its values through the Blender Python API.

Custom properties in the Blender Python API can be limited to setting with maximum and minimum values. In this case, the user, entering the desired value to the property field, will not be able to set a value that goes beyond the specified limits.
To set the minimum and maximum limits, we can specify the “min” and “max” parameters in our custom property and assign them the necessary limiting values.
For quickly finding the desired node in the Node Editor in the search box it is enough to type only the first letters from the node’s name.
This method works both in the shader node editor and in the Geometry Nodes search system.
For example, to search for the “Set Curve Radius” node, it is enough to type only the “SCR” letters in the search field. And to search for the “Principle BSDF” node, just type “PB”.
