The main() module in the starter code below takes integar inputs separated by commas from the user and stores them in a list. Then, it allows the user to manipulate the list using 3 functions: mutate_list() takes 3 parameters -- a list, index number, and a value -- and inserts the value in the position specified by the index number in the list.
remove_index() takes 2 parameters -- a list and an index number -- and remove the element at the position number indicated by index. It also prints the total number of elements in the list before and after removing the character in this fashion:"Total elements in list = 11
Total elements in list = 10"
reverse_list() takes 1 parameter -- a list -- and returns the list reversed.
Examples:
Example 1:
Enter values in list separated by commas: 1,2,4,63,6,4,22,53,76
[1, 2, 4, 63, 6, 4, 22, 53, 76]
Menu:
mutate list(m), remove (r), reverse_list (R)
Enter choice (m, r,R): m
4,45
[1, 2, 4, 63, 45, 6, 4, 22, 53, 76]
Example 2:
Enter values in list separated by commas: 1,2,4,6,84,3,2,2,76
[1, 2, 4, 6, 84, 3, 2, 2, 76]
Menu:
mutate list(m), remove (r), reverse_list (R)
Enter choice (m, r,R): R
[76, 2, 2, 3, 84, 6, 4, 2, 1]
Example 3:
Enter values in list separated by commas: 12,2,3,5,2,6,2,1,2,333,65
[12, 2, 3, 5, 2, 6, 2, 1, 2, 333, 65]
Menu:
mutate list(m), remove (r), reverse_list (R)
Enter choice (m, r,R): r
Example 4
Total elements in list = 11
Total elements in list = 10
[12, 2, 3, 5, 6, 2, 1, 2, 333, 65]
please use the codes below
def main():
user_list = input("Enter values in list separated by commas: ")
user_list = user_list. split(",")
user_list = [int(i) for i in user_list]
print(user_list)
print("Menu: ")
print("mutate list(m), remove (r), reverse_list (R)")
user_choice = input("Enter choice (m, r,R): ")
if user_choice == 'm':
index_num, v = input().split(",")
index_num = int(index_num)
v = int(v)
mutate_list(user_list, index_num, v)
print(user_list)
elif user_choice == 'r':
index_num = int(input())
remove_index(user_list, index_num)
print(user_list)
elif user_choice == 'R':
new_list = reverse_list(user_list)
print(new_list)
