Question C$2[10$ marks$]$

Write your answer in the provided file A$3$Q$2.$ py$.$ Fill in your name and student ID in the designated section.

This application is used in a fruit store to calculate the amount spent on each order, maintain records, and generate a daily report or log file for all orders.

The fruit names and their corresponding prices $($per gram$)$ are stored in a text file named "productsList. txt$"$ with the format $"=".$ Each line in the file contains one 'fruit$-$price' pair, as shown in the sample below:

To implement this application, you need to define a few functions:

$1.$ Write a function read$\_$data$()$ with the filename as the input parameter and return a list of strings holding all contents of this file.

$2.$ Write a function list$\_$to$\_$dict$()$ with aList as input parameter and return a dictionary. Below is test case for this function:

$```$

$>>>$ listTest $=[\text{'}$Fruit $1=0\mathrm{.}02$

$\text{'},$'Fruit $2=0\mathrm{.}03$

$\text{'},$'Fruit $3=0\mathrm{.}04$

$\text{'}]$

$>>>$ dictTest$=$list$\_$to$\_$dict$($listTest$)$

$>>>$ print$($dictTest$)$

$\{\text{'}$Fruit $1\text{'}$: $0\mathrm{.}02,$ 'Fruit $2\text{'}$: $0\mathrm{.}03,$ 'Fruit $3\text{'}$: $0\mathrm{.}04\}$

$```$

$3.$ Write a function cust$\_$spend$)$ with adict as parameter. Iterate through all the item keys in the dictionary adict, and prompt the user to enter the weight $($in grams$)$ for each fruit. The function should calculate the total amount of the order and return it as an output in float format. Below is the test case for this function:

$```$

$>>>$ f$\_$test$=$cust$\_$spend$($dictTest$)$

How many grams of the fruit 'Fruit $1\text{'}[$price:$0\mathrm{.}02]?100$

How many grams of the fruit 'Fruit $2\text{'}[$price:$0\mathrm{.}03]?100$

How many grams of the fruit 'Fruit $3\text{'}[$price:$0\mathrm{.}04]?100$

$>>>$ print$($f$\_$test$)$

$9\mathrm{.}0$

$```$

$4.$ Write a function main$()$ as the main loop of this application. Inside the main$()$ function, do the following:

a$.$ Load the fruit$-$price information by opening the given text file "productsList.txt$"$ and reading the contents into a variable ls$\_$allPrices as a list.

b$.$ Convert this list to a dictionary dict$\_$ProductPrice by calling the corresponding function.

c$.$ Use a while True loop to ask the user for customer ID$,$ and store it in a variable customerID. Print the greeting messages $($see the sample output$)$ and ask the user to enter the weights for each fruit $($by calling the cust$\_$spend $()$ function$).$ Print the total amount of the order. Exit this loop when the user enters the word 'end'.

d$.$ Store each order in a tuple with the format $","$ Create a variable todayOrder as a list and add each tuple record to the list todayOrder.

e$.$ Display the variable todayOrder after the user entered the word 'end' as a customerID. The total amount should be displayed with $2$ decimal places.

$5.$ The program output should adhere to the Sample Output provided below:

Sample Output $1$:

$```$

Completed by student Chan Siu Ming with student ID $40202425.$

Please enter your customer ID $[$type 'end' to exit$]$: $1001$

Hi$,1001!$ Please enter the weight$[$in grams$]$ for each fruit:

How many grams of the fruit 'Apple'$[$price:$0\mathrm{.}04]?100$

How many grams of the fruit 'Banana'$[$price:$0\mathrm{.}15]?100$

How many grams of the fruit 'Grape'$[$price:$0\mathrm{.}1]?100$

Thank you, $1001!$ You have spent $$29\mathrm{.}00$ in this order.

Please enter your customer ID $[$type 'end' to exit$]$: $1002$

Hi$,1002!$ Please enter the weight$[$in grams$]$ for each fruit:

How many grams of the fruit 'Apple'$[$price:$0\mathrm{.}04]?10$

How many grams of the fruit 'Banana'$[$price:$0\mathrm{.}15]?10\mathrm{.}05$

How many grams of the fruit 'Grape'$[$price:$0\mathrm{.}1]?10\mathrm{.}5$

Thank you, $1002!$ You have spent $$2\mathrm{.}96$ in this order.

Please enter your customer ID $[$type 'end' to exit$]$: end

Today's orders: $[(\text{'}1001\text{'},\text{'}29\mathrm{.}00\text{'}),(\text{'}1002\text{'},\text{'}2\mathrm{.}96\text{'})]$

$```$

Sample Output $2($No order has been made.$).$

$```$

Completed by student Chan Siu Ming with student ID $40202425.$

Please enter your customer ID $[$type 'end' to exit$]$: end

Today's orders: $[]$

$```$

Note:

$-$ All user inputs are in green.

$-$ Assume the user inputs for the weights are all in numeric data types.

$-$ Assume the provided file "productsList. txt$"$ contains the sample data and exists in the same directory as the Python file A$3$Q$2.$ py$.$

$-$ Ensure that all mentioned variables $(1$s$\_$allPrices, todayOrder, dict$\_$ProductPrice, customerID$)$ are used and assigned appropriate values.

Hint: Refer to the general guidelines to determine how to call the main $()$ function.
