List slicing: • Slicing is a concept of selecting a range of elements from a list. • In Python, the expression that selects a subsection of a list is known as a slice. • A slice is a span of data that are taken from a list. • Normally, the slice expression has a start index and an end index for slicing. • In case if the end index is not provided, the python employs the length of the list as the end index. Syntax: In Python, the list slice statement without the end index can be expressed as follows: listname[start:] Explanation: In the list slice syntax, • The “start” represents the index of the first data in the slice. • 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 list having a copy of data from index “start” up to the end of the list.

Question

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]

Chapter 7.3, Problem 10CP

Program Plan Intro

List slicing:

• Slicing is a concept of selecting a range of elements from a list.

• In Python, the expression that selects a subsection of a list is known as a slice.

• A slice is a span of data that are taken from a list.

• Normally, the slice expression has a start index and an end index for slicing.

• In case if the end index is not provided, the python employs the length of the list as the end index.

Syntax:

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

listname[start:]

Explanation:

In the list slice syntax,

• The “start” represents the index of the first data in the slice.

• 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 list having a copy of data from index “start” up to the end of the 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

paython programing question Write a program that creates a list of N elements (Hint: use append() function), swaps the first and the last element and prints the list on the screen. N should be a dynamic number entered by the user. Sample output: How many numbers would you like to enter?: 5 Enter a number: 34 Enter a number: 67 Enter a number: 23 Enter a number: 90 Enter a number: 12 The list is: [12, 67,23, 90, 34]
