Does operator exist?

__init__.py

import bpy

def operator_exists(idname):
    # Split the idname string into the operator type and the operator function
    idname_parts = idname.split(".")
    
    if len(idname_parts) != 2:
        return False  # The idname is not properly formatted
    
    operator_type, operator_func = idname_parts
    
    # Check if the operator type and function exist in bpy.ops
    return hasattr(getattr(bpy.ops, operator_type, None), operator_func)

# Example usage:
print(operator_exists("sequencer.generate_image"))  # Returns True if the operator exists
