Lottery number generator: Write a program that generates aseven-digit lottery number. The program should have a loopto generate seven random numbers, each in the range 0through 9 and assign each number to a list element.2. Write another loop to display the contents of the list.3. Tip: You will need to create/initialize your list before you canassign numbers to it.4. Use program 7-1 sales_list as an example. You will start witha seven-digit lottery number that contains all zeros. Then inyour loop, you will assign a random number instead ofgetting the data from the user.Turn in your program to the practice assignment link in coursecontent.
Assume that the variable data refers to the list [5, 3, 7]. Write the expressions that perform the following tasks: a. Replace the value at position o in data with that value's negation. b. Add the value 10 to the end of data. c. Insert the value 22 at position 2 in data. d. Remove the value at position 1 in data. e. Add the values in the list newData to the end of data. f. Locate the index of the value 7 in data, safely. g. Sort the values in data.
python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.
Largest Value. Create a program that uses a list to store input values, and outputs the largest value entered at its location in the list. The program shall accept input values until the user enters -1. And Next Movie Time. Create a program that shows the user when the next showing for a movie is. The program first reads the different showing times (only hours) in a 24-hour clock format (that is, 1PM is 13, 6PM is 18, etc.). The program then asks when a customer wants to go to the movies. The program replies with the time for the next showing. If the next showing matches the hour input by the customer, show the next showing after that. If the next showing is past the last one, the program shall output, “There are no more showings.”, Here is a sample execution: I am trying to use these programs as practice for practicing lists, strings and inputs. But am struggling a bit after laying down the foundation on each problem. I plan to put them into thonny to compare them with my own work.
Matich the following statements with the correct data structure by clicking on the drop down arrow and selecting the correct choice.. You need to store a list of elements and the number of elements in the program is fixed. If most of operations on a list involve retrieving an element at a given index. You have to add or delete the elements at the beginning of a list. Linked List ArrayList Array
A code segment is intended to transform the list utensils so that the last element of the list is moved to the beginning of the list. For example, if utensils initially contains ["fork", "spoon", "tongs", "spatula", "whisk"], it should contain ["whisk", "fork", "spoon", "tongs", "spatula"] after executing the code segment. Which of the following code segments transforms the list as intended? len + LENGTH (utensils) temp + utensils[len) REMOVE (utensils, len) APPEND (utensils, temp) A len + LENGTH(utensils) REMOVE (utensils, len) B temp + utensils[len) APPEND (utensils, temp) len + LENGTH (utensils) temp + utensils[len] REMOVE (utensils, len) INSERT (utensils, 1, temp) len + LENGTH(utensils) REMOVE (utensils, len) D temp + utensils[len] INSERT(utensils, 1, temp)

Data structures remove_char(str_list:list, char:str) -> list This function will be given a list of strings and a character. You must remove all occurrences of the character from each string in the list. The function should return the list of strings with the character removed. Example: str_list = ['adndj', 'adjdlaa', 'aa', 'djoe'] char: a output = ['dndj', 'djdl', '', 'djoe']
# This function takes a list of points and returns a new list of points, # beginning with the first point and then at each stage, moving to the closest point that has not yet been visited.# Note: the function should return a new list, not modify the existing list.# Hint: use a while loop to repeat while the list of remaining points is not empty
