Replace In List

The Replace In List node allows you to replace an item in a list either by matching the item or by its index.

Inputs

• Items (list): The list to modify
• Item To Replace (any): The item to replace in the list (shown when Replace By is "item")
• Index To Replace (int): The index of the item to replace (shown when Replace By is "index")
• New Item (any): The new item to replace with

Properties

• Replace By (str): How to identify the item to replace
  • Options:
    • "item": Replace by matching the item value
    • "index": Replace by index position

Outputs

• Output (list): The modified list with the item replaced

Example

# Input list: [1, 2, 3, 4]

# Replace by item:
# Item To Replace: 3
# New Item: "three"
# Output: [1, 2, "three", 4]

# Replace by index:
# Index To Replace: 1
# New Item: "two"
# Output: [1, "two", 3, 4]

Notes

• When replacing by item, the first occurrence of the item will be replaced
• When replacing by index, the index must be within the bounds of the list
• If the item is not found when replacing by item, no changes will be made
• The original list is not modified; a new list is returned
