Create a program that will allow a user to add, list, and delete items from a shopping list.

Deliverables
• A source code Python file.
• A Word document containing both source code and the screen print of the program outputs.

Lab Steps
The program should be modular. For example, you will want to have an add_item(shopping_list) function, a delete_item(shopping_list) function, a display_list(shopping_list) function, a display_menu() function, and a main().

Sample Output:
Welcome to the program!
1. Add an item
2. List all items
3. Delete an item
4. Exit

Enter a menu option: 2
1 : bananas
2 : apples

Enter a menu option: 1
Please enter the item: pears
pears was added to the shopping list

Enter a menu option: 2
1 : bananas
2 : apples
3 : pears

Enter a menu option: 3
Which number to delete: 3
pears was deleted

Enter a menu option: 2
1 : bananas
2 : apples

Enter a menu option: 4
have a great day!

Specifications:
• The program should start with 2 items in the shopping list.
• Don’t forget to include at the end of the program the code:
o if __name__ == “__main__”:
main();
• Use this code for the delete_item(shopping_list) function:
def delete_item(shopping_list):
number=int(input(“Which number to delete: “))
if number<1 or number>len(shopping_list):
print(“Invalid number\n”)
else:
item=shopping_list.pop(number-1)
print(item,” was deleted\n”)
print()

Store the times into arrays called Chevy[ ] and Ford[ ]. Then list the winner of each pair, giving the number of seconds the winner won by. At the end declare which team won based on which team had the most wins.

Deliverables
• A source code Python file.
• A Word document containing both source code and the screen print of the program outputs.

Lab Steps
There are eight cars in each team called Chevy and Ford. One car from each team races its opponent on the drag strip. Read in the racing times for the eight Chevy cars and then read in the times for the eight Ford cars.

Sample Match:
—Input Chevy Times—
Enter time for Chevy Car 1: 5.4
Enter time for Chevy Car 2: 7.2
Enter time for Chevy Car 3: 4.0
Enter time for Chevy Car 4: 9.1
Enter time for Chevy Car 5: 5.8
Enter time for Chevy Car 6: 3.9
Enter time for Chevy Car 7: 6.2
Enter time for Chevy Car 8: 8.1
—Input Ford Times—
Enter time for Ford Car 1: 5.8
Enter time for Ford Car 2: 6.9
Enter time for Ford Car 3: 3.9
Enter time for Ford Car 4: 9.2
Enter time for Ford Car 5: 5.8
Enter time for Ford Car 6: 3.8
Enter time for Ford Car 7: 6.0
Enter time for Ford Car 8: 8.5
And the winners are:
Chevy by 0.4 sec
Ford by 0.3 sec
Ford by 0.1 sec
Chevy by 0.1 sec
Tie!
Ford by 0.1 sec
Ford by 0.2 sec
Chevy by 0.4 sec
And the winning team is: F O R D !

Specifications:
• Accept the racing times for each of the Chevy cars into the array Chevy[ ].
• Accept the racing times for each of the Ford cars into the array Ford[ ].
• Then declare the wining car for each race, giving the winning time in seconds.
• If the times are identical, then declare the race was a tie.
• Finally, declare which team won the match, assuming a tie is possible.

This week’s lab is to create a simple multiplication table using nested loops and if statements.
Prompt the user for the size of the multiplication table (from 2×2 to 10×10). Use a validation loop to display a warning if the number is less than 2 or greater than 10 and prompt the user to enter the data again until they enter a valid number.
Put a # after any even number in your table (odd numbers will have just a space/nothing after them).

Deliverables
• A source code Python file.
• A Word document containing both source code and the screen print of the program outputs.

Lab Steps

Sample Output:
The output should be something similar to the following.
What size multiplication table would you like? (2 – 10): 1
Invalid entry – Enter a number between 2 and 10
What size multiplication table would you like? (2 – 10): 15
Invalid entry – Enter a number between 2 and 10
What size multiplication table would you like? (2 – 10): 10

10 |    10 #   20 #   30 #   40 #   50 #   60 #   70 #   80 #   90 #  100 #

Hints:
• The outer loop will start each new row.
• The inner loop will control the display of each column in the row.
• Note that to keep the numbers right-aligned, there are different amounts of space before single digit numbers (those less than 10), double digit numbers (those between 10-99), and triple digit numbers (100).
• The row labels can be added to your inner loop (note that there are different amounts of space required after the number in the row labels.
• The column labels should use a separate loop(s) that run before the main outer loop.
• You can continue printing on the same line using end=”” in your print statement. This will come in handy if you want to print several things on one line inside a loop. For example, assuming the value of name is Ada, the following will print “Hello Ada” on one line:
print(“hello “, end=””)
print(name, end=””)

Tips:
• Start early!
• Do the basic table first without worrying about spacing or lining things up, and don’t include row or column headings (add those later).
• Once you get the numbers in the correct position, think about adding the proper amount of space before each number to line things up.
• Once the columns line up, add the #/space for even/odd numbers.
• Once the basic table is working, then add the row and column headings, and finally the main title.
