Python: On-line Grocery Shopping Use grocery py in Canvas to start your program. It contains two dictionaries: stock and price EX: stock key/value pairs EX: price key/value pairs tomato soup 20 tomato soupP 1.85 cheese 10 cheese 3.99 Create a two functions: first called grocery_cost(food), where food can be one item or a list of items from the stock and price dictionaries, the second is called stock_check(stock_list) where a store manager can check if stock numbers are at a minimum value. The first function loops through the argument food, notes the price, checks the stock, calculates and prints the total cost and changes the stock number. You will need to use a for statement to loop through the items in food and an if statement to check and update the stock. The second function loops through each item in the stock dictionary and uses an if- statement to determine if stock is less than 5.
2.16 LAB: Musical note frequencies On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of fO * r^, where n is the distance (number of keys) from that key, and r is 20/12) Given an initial key frequency, output that frequency and the next 4 higher key frequencies.
Chapter 5. PC #17. Rock, Paper, Scissors Game (page 317) Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 2. When the program begins, a random number in the range of 0 through 2 is generated. If the number is 0, then the computer has chosen rock. If the number is 1, then the computer has chosen paper. If the number is 2, then the computer has chosen scissors. (Do not display the computer choice yet.) 3. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. You should use 1 for rock, 2 for paper, and 3 for scissors. Internally, you can store 0, 1, and 2 as the user choice, to match with the above schema. 4. Both user and computer choices are displayed. 5. A winner is selected according to the following rules: If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) If one player chooses scissors and…
A1.2 Bean MachineThe bean machine is a device for statistical experiments. It consists of an upright board with evenly spaced nails (or pegs) in a triangular form,.Balls are dropped from the opening at the top of the board. Every time a ball hits a nail, it has a 50% chance of falling to the left or to the right. The piles of balls are accumulated in the slots at the bottom of the board.Write a program to simulate the bean machine that has 8 slots as shown in the figure. Your program should prompt the user to enter the number of balls to drop. Simulate the falling of each ball by printing its path. For example, the path for the ball in LLRRLLR and the path for the ball in RLRRLRR. Note that there are 7 levels of nails, so your path should be 7 letters (not 8).Create an array called slots. Each element in slots store the number of balls in a slot. Each ball falls into a slot via a path. The number of “R”s in a path is the position of the slot where the ball falls. For example, for the…
3.8: Software SalesA software company sells a package that retails for $99. Quantity discounts are given according to the following table:Quantity Discount10-19 20%20-49 30%50-99 40%100 or more 50%Write a program that asks the user to enter the number of packages purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount. For instance, to calculate 20% of a value N, you can use the formula:(20 / 100.0) * N (or 0.2 * N).

3.6 LAB: Number pattern Write a recursive function called print_num_pattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For coding simplicity, output a space after every integer, including the last. Do not end output with a newline Ex. If the input is: 12 3 the output is 12 9 6 3 0 3 6 9 12 0/10 LAB ACTIVITY 3.6.1: LAB: Number pattern main.py Load default template 1.

C++ ONLYTomorrow is the closing ceremony for the 2022 World Cup, and Cody and his friends want to know who the top scorer of the tournament is. John and the others insist that it Lionel Messi who is the top-scorer (scoring 10) but Cody, a Ronaldo fan, is stubborn and decided to make a list of all the players who scored goals and order them randomly. He then must look for the highest number and see if that number is higher than Messi’s goals. Input the number of players then input the number of goals scored for each. Print "Not Messi" if the highest goals exceed 10 and "Okay, fine, it's Messi" if it doesn’t.Enter·the·number·of·players:·4 Goals·score·by·player·#1:·7 Goals·score·by·player·#2:·2 Goals·score·by·player·#3:·5 Goals·score·by·player·#4:·1 Okay,·fine,·it's·Messi
