5:28 K Back Hwrk06,pdf Q If we look closely at Program 6-15, we will notice that there are only two things that we must change if we wish to make it into a Module containing a function that we will use in the driver program. First we must change the name of the main function to another name. We will use the name: add_coffee() as the name of what was called main)- * The second thing we must do is to delete the very last line of this program ine 32, main()), as this module will not call this function, rather it will be the driver program which calls this function Once we have made these two changes, then the program which was labelled Program6-15, we will call module: Lastnomefirstinitial coffiee records.py, and it will contain a function, add coffee), that we will be using in the Driver program Program 6-15 (add coffee_record py) 1 This program adds coffee inventory records to 2 # th@ coffee. txt file 4 det nain) Create a variable to control the loop. another ' Opene coffee coffee tile open( coffee.txt. #Add records to the file 12 13 14 15 16 17 18 19 20 21 Get the coffee record data. print( Enter the folloving coffee datas"1 descr input ( Descriptions t Append the data to the file coffee file.write(descr' coffee file.writelatriqty) Appen Determine whether the user vants to add i another record to the file print Do you vant to add another reoord?") anotherInput( 'Y -yes, anything else 27 28 i Close the file. coffee_file.cloael) print( Data appended to coffee.txt 30 31 Call the main function Program 6-15 Results Dashboard Calendar To Do Notifications Inbox 5:28 Back Hwrk06.pdfa Program Output (with input shown in bold) Enter the folloving coffee data Description: Brazilian Dark Roast Quantity (in pounds) : 18r Do you want to enter another record2 xyes, anything else -nosy t Description: Sumatra Medium Roast Quantity (in pounds): 25 Do you want to enter another record? Y yes, anything else nos n Data appended to coftee.txt Homework 06 Cont. Now that we have one module, we are going to write the driver for this module: YourName-Hwrk06.py Initially, this driver will just run this first module. However, after you've got the first module working, you will be expanding this driver to include 4 additional modules. Below is the essence of the driving program which will run this File Management System to test and run the module LastnameFirstinitial coffee_records.py YourName-Lab06. nagement Program Calendar To Do Inbox 5:29 Back Hwrk06.pdf Q # Your Name # A Coffee File Management Program import Valdez)-coffee-records # Here's where we import th ADD COFFEE CHOICE 1 # Define Global constants fo # Which includes the choice QUIT_CHOICE 6 def main(): choice0 while choice!-QUIT_CHOICE: display menu() choice = int(input('Enter your choice:1) if choiceADD_COFFEE_CHOICE: Valdezl coffee recordsadd-coffee() print(Exiting the progra...) print('Error: invalid selection.') # We call the fun elif choice QUIT-CHOICE else: def display_menu0 print(JUAN VALDEZ COFFEE MANAGEMENT MENU) print'1) Add more Coffee Choices to List'T print(6) Quit') main() Home Once you have the first will repeat what you did Program 6-16, which co Then you will expand th this additional module Calendar To Do Inbox 5:29 Back Hwrk06.pdfa QUIT CHOICE linputfEnber your choice ADD COFFEE CHOE QUIT CHOICE ror: invalid selection VALDEZ COFFEE MANAGEMENT MENU more Coffee Choices to List Homework 06 Cont. Once you have the first module up and running, now you will repeat what you did and add to the module, the second Program 6-16, which contains the function show_coffee(). Then you will expand the driver program menu to include this additional module You will also import this module You will change the menu to indlude this module Once the second function is working, repeat the preceding 3 more times to include: Program 6-17, Program 6-18 and Program 6-19 From these three programs you will be adding the following functions to your module: LastnameFirstinitial coffee records search_coffee) modify_coffee) Modify your driver program to accommodate these additions progran dispiaye the oetfee.sxt ie Program 6-16 oed the EL Pcoreaerieion tinia.
