6. sum_highest_five This function takes a list of numbers, finds the five largest numbers in the list, and returns their sum. If the list of numbers contains fewer than five elements, raise a ValueError with whatever error message you like. Sample calls should look like: >>> sum_highest_five([10, 10, 10, 10, 10, 5, -17, 2, 3.1])50>>> sum_highest_five([5])Traceback (most recent call last): File "/usr/lib/python3.8/idlelib/run.py", line 559, in runcode exec(code, self.locals) File "<pyshell#44>", line 1, in <module> File "/homework/final.py", line 102, in sum_highest_five raise ValueError("need at least 5 numbers")ValueError: need at least 5 numbers
