ComfyUI Node: LogicUtil_Random Shuffle Int

LogicUtil_Random Shuffle Int:

The LogicUtil_RandomShuffleInt node is designed to take a list of integers, shuffle them randomly, and return the shuffled list. This node is particularly useful when you need to randomize the order of a sequence of numbers, which can be beneficial in various creative and computational tasks. By providing a seed value, you can ensure that the shuffling process is reproducible, meaning the same input and seed will always produce the same shuffled output. This feature is especially valuable for maintaining consistency in randomized processes across different runs.

LogicUtil_Random Shuffle Int Input Parameters:

input_string

This parameter takes a string of integers separated by a specified delimiter. The string is split into individual integers based on the separator, which are then shuffled. The default value is "1$2$3", meaning the integers 1, 2, and 3 will be shuffled. This parameter allows you to define the list of integers you want to shuffle.

separator

The separator parameter specifies the character used to split the input_string into individual integers. The default value is "$". This allows you to customize how the input string is parsed, making it flexible to different formats of input data.

seed

The seed parameter is an integer that initializes the random number generator used for shuffling. The default value is 0, and it can range from 0 to 9999999999. By setting a specific seed, you can ensure that the shuffling process is reproducible, which is useful for debugging and consistency in results.

LogicUtil_Random Shuffle Int Output Parameters:

STRING

The output is a single string that contains the shuffled list of integers, separated by the same delimiter used in the input. This output allows you to easily see the new order of the integers after shuffling, which can then be used in subsequent nodes or processes.

LogicUtil_Random Shuffle Int Usage Tips:

• To ensure reproducibility in your shuffling process, always set a specific seed value.
• Use a unique separator that does not appear in your list of integers to avoid incorrect splitting of the input string.
• If you need to shuffle a large list of integers, ensure that the input string is formatted correctly to prevent errors during the splitting process.

LogicUtil_Random Shuffle Int Common Errors and Solutions:

"IndexError: list index out of range"

• Explanation: This error occurs if the input string is not properly formatted or if the separator does not correctly split the string into integers.
• Solution: Ensure that the input string is correctly formatted and that the separator is correctly specified.

"ValueError: invalid literal for int() with base 10"

• Explanation: This error occurs if the input string contains non-integer values or if the separator is incorrect.
• Solution: Verify that the input string contains only integers and that the separator correctly splits the string into valid integer values.

"TypeError: 'NoneType' object is not iterable"

• Explanation: This error occurs if the input string is empty or if the separator does not match any character in the input string.
• Solution: Ensure that the input string is not empty and that the separator is correctly specified to match the characters in the input string.
