This Python script provides advanced parsing and scheduling functionality for prompts in Stable Diffusion models. It supports:

Weighted and scheduled prompt modifications using brackets ([ ], ( ), { }) and the separator :.
Parsing complex prompt structures for conditional generation, including grouped descriptions and de-emphasis weights.
Multiconditional learned conditioning with support for dynamic scheduling over sampling steps.
Attention parsing for fine-grained control over prompt focus (e.g., [(word:1.2)] for emphasis).
