To determine the length of the list we use the ___ function.Group of answer choiceslength()()lengthlen()()len

To determine the length of a list in Python, you use the len() function. This built-in function takes an iterable (like a list, tuple, or string) as an argument and returns the number of items in that iterable.

Here's how the len() function works:

1. Function Definition: The len() function is defined as part of Python's built-in functions, meaning it doesn't require importing any modules to use.

2. Syntax: The syntax for using the len() function is:

   length = len(iterable)
   

   where iterable can be a list, string, or any other collection type.

3. Example: For example, if you have a list like:

   my_list = [1, 2, 3, 4, 5]
   

   you can find its length by:

   length_of_list = len(my_list)
   print(length_of_list)  # This will output: 5
   

Hence, based on the options given, the correct choice is len().

Final Answer

The correct answer is len().
