ComfyUI Node: Any List Iterator

Any List Iterator:

The Any List Iterator node is designed to help you efficiently access elements from a list based on a given counter. This node is particularly useful when you need to iterate over a list of items, such as images, text, or any other data types, in a cyclic manner. By leveraging the counter, the node ensures that you can continuously loop through the list without running into index out-of-bounds errors. This functionality is essential for tasks that require repeated access to list elements, such as generating sequences or applying transformations to a series of items.

Any List Iterator Input Parameters:

counter

The counter parameter is an integer that determines the current position in the list from which to retrieve an element. The value of the counter is taken modulo the length of the list to ensure it wraps around when it exceeds the list length, allowing for continuous iteration. The default value is 0, and it can be any integer.

list

The list parameter is the list of items you want to iterate over. This list can contain any type of elements, such as numbers, strings, or custom objects. The node will use the counter to select an element from this list.

Any List Iterator Output Parameters:

AXIS_VALUE

The AXIS_VALUE output is the element from the list at the position specified by the counter. This output allows you to retrieve and use the selected element in subsequent nodes or operations. The type of this output will match the type of the elements in the input list.

Any List Iterator Usage Tips:

• Use the counter parameter to control the iteration over the list. Increment the counter in a loop or based on specific conditions to access different elements.
• Ensure that the list parameter is not empty to avoid errors. You can use nodes like Any List to create and manage your lists dynamically.

Any List Iterator Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error occurs when the list is empty, and the counter tries to access an element.
• Solution: Ensure that the input list is not empty before using the Any List Iterator node. You can add a check or use a default list with at least one element.

TypeError: unsupported operand type(s) for %: 'int' and 'NoneType'

• Explanation: This error occurs when the counter or list is not properly initialized or is set to None.
• Solution: Make sure that the counter is an integer and the list is properly defined and not None. Initialize these parameters correctly before using the node.
