ComfyUI Node: FromListGet1Float

FromListGet1Float:

The FromListGet1Float node is designed to extract a single float value from a list of floats based on a specified index. This node is particularly useful when you need to access specific elements within a list of floating-point numbers, allowing for precise control and manipulation of data. By providing an index, you can retrieve the corresponding float value from the list, making it easier to work with individual elements in various AI art and computational tasks. This node supports both positive and negative indexing, enabling flexible access to list elements from the beginning or the end.

FromListGet1Float Input Parameters:

list

The list parameter expects a list of float values from which a single float will be extracted. This input is crucial as it provides the data source for the node to operate on. The list should contain valid float numbers, and the node will use the specified index to retrieve the corresponding float value from this list. Ensure that the list is not empty and contains the necessary float values for accurate extraction.

index

The index parameter specifies the position of the float value to be retrieved from the list. It accepts integer values, including negative integers for reverse indexing. The default value is 0, which corresponds to the first element in the list. The index value is automatically adjusted to fit within the bounds of the list, ensuring that it wraps around if it exceeds the list length. This parameter allows you to pinpoint the exact float value you need from the list.

FromListGet1Float Output Parameters:

FLOAT

The output parameter FLOAT represents the single float value extracted from the list based on the specified index. This output is crucial for further processing or analysis, as it provides the exact float value needed for subsequent operations. The extracted float can be used in various computational tasks, making it a versatile and essential output for AI art and other applications.

FromListGet1Float Usage Tips:

• Ensure that the list provided contains valid float values to avoid errors during extraction.
• Utilize negative indexing to easily access elements from the end of the list without needing to calculate the exact position.
• Use the node in combination with other list manipulation nodes to streamline data processing workflows.

FromListGet1Float Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error occurs when the specified index is out of the bounds of the list.
• Solution: Ensure that the index value is within the valid range of the list length. The node automatically adjusts the index, but double-checking the list size can prevent this error.

TypeError: list must contain float values

• Explanation: This error occurs when the list contains non-float values.
• Solution: Verify that all elements in the list are valid float numbers before passing it to the node.
