Program Plan Intro

List slicing:

  • • Slicing is a concept of selecting a range of elements from a list.
  • • In Python, an expression that selects a subsection of a list is known as a slice.
  • • A slice is a span of elements that are taken from a list.
  • • Normally, the slice expression has a start index and an end index for slicing.
  • • In case if the start and end indices are not provided, the python employs 0 as the start index and length of the list as the end index.

Syntax:

In Python, the list slice statement without the start index and end index can be expressed as follows:

listname[:]

Explanation:

In the list slice syntax,

  • • As the “start” index is not provided, python uses 0 as the start index by default.
  • • As the “end” index is not provided, Python employs the length of the list as the “end” index for the slice.
  • • The list slice expression returns a copy of the entire list.

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
reverse_number_in_list(number_list:list)-> list 
This function will be given a list of numbers your job is to reverse all the numbers in the list and return a list with the reversed numbers. If a number ends with 0 you need to remove all the trailing zeros before reversing the number. An example of reversing numbers with trailing zeros:  10 -> 1,  590 -> 95. None of the numbers in the number_list will be less than 1.  Example: number_list = [13, 45, 690, 57] output = [31, 54, 96, 75]
Pyhton code please help, indentation would be greatly appreciated
