What function is used to join values from a list using a defined separator?

The function that is used to join values from a list using a defined separator is indeed 'join()'. This method is a string method that takes all items in an iterable, such as a list, and concatenates them into a single string by placing the defined separator between each item.

For example, if you have a list of words like ["apple", "banana", "cherry"] and you want to join them into a single string with commas in between, you would use the join method like this:

separator = ", "

result = separator.join(["apple", "banana", "cherry"])

print(result)  # Output: "apple, banana, cherry"

In this case, separator contains the string that serves as the delimiter between the items being joined.

The other functions listed serve different purposes:

• 'append()' is used to add elements to a list.

• 'sorted()' is used to return a new sorted list from the specified iterable.

• 'max()' is used to find the maximum value from an iterable or two or more arguments.

These functions do not relate to the task of concatenating elements with a specified separator, which clearly highlights why 'join()' is
