AttributeError: ‘list’ object has no attribute ‘update’ error occurs when you try to operate the update() method on the list object, which does not exist.
Reproduce the error
numbers = [1, 2, 3] numbers.update(4) print(numbers)
How to fix the error?
Here are three ways to fix the error.
Solution 1: Using the list.append()
You can use the list append() method to add elements to a list.
numbers = [1, 2, 3] numbers.append(4) print(numbers)
Solution 2: Using the list.extend()
The list.extend() method extends the list by appending all elements from an iterable-like list.
numbers = [1, 2, 3] digits = [11, 21, 31] numbers.extend(digits) print(numbers)
Solution 3: Using the list.insert()
The list.insert() method will help you add an item at a specific index rather than at the end.
I hope you will use one of these three methods instead of the update() method to prevent the error.
