Task $03(20$ points$)$ Task $04(20$ points$)$

Write a Python program that completes the following steps:

Create a list named fruits containing the following elements: "Apple", "Banana", "Cherry",

"Date", "Elderberry".

Print the list.

Convert the fruits list to a tuple named fruits$\_$tuple.

Print the tuple.

Convert the fruits list to a set named fruits$\_$set.

Print the set.

Convert the fruits list to a dictionary named fruits$\_$dict that contains the fruits as keys and

their lengths as values:

a$.$ Lengths being the size of the word $($key$)-$ Apple is $5,$ Banana is $6,$ but these

should not be hardcoded values, you need to use the len$()$ function to gather the

length of the key.

Print the dictionary.

Add "Fig" and "Grape" to the fruits list.

Remove "Date" from the fruits list.

Print the updated list.

Update fruits$\_$dict to reflect the changes made to the fruits list.

Print the updated dictionary.

Write a Python program that contains multiple user$-$defined functions that calculate storage

requirements and costs. These functions will provide useful metrics in the context of data

storage and backup solutions. Perform the following steps:

Create a function named calculate$\_$backup$\_$size that takes two arguments: data$\_$size $($in

gigabytes$)$ and backup$\_$frequency. This function should return the data$\_$size multiplied

by backup$\_$frequency, representing the total storage needed for backups in a week.

Create another function named calculate$\_$storage$\_$cost that takes two arguments:

backup$\_$size and cost$\_$per$\_$gb$.$ This function should return the value of backup$\_$size

multiplied by cost$\_$per$\_$gb$,$ representing the total cost for the backup storage.

Create a third function named storage$\_$info that takes four arguments: data$\_$size,

backup$\_$frequency, cost$\_$per$\_$gb$,$ and weeks. This function should call

calculate$\_$backup$\_$size and calculate$\_$storage$\_$cost functions, taking the appropriate

arguments. Then it should multiply the cost by the number of weeks. It should return a

string that says "The total storage needed for backup is $x$ GB and the total cost for $Y$

weeks is $Z$ dollars", replacing $x,Y,$ and $Z$ with the calculated values.

Prompt the user to enter values for data$\_$size, backup$\_$frequency, cost$\_$per$\_$gb$,$ and

weeks. If the user does not enter a positive number, your program should catch this error

and ask for the input again.

Call the storage$\_$info function with the user$-$provided data$\_$size, backup$\_$frequency,

cost$\_$per$\_$gb$,$ and weeks and print the returned string.

Provide comments in your code to explain the logic used.

Test your program with different inputs and ensure it performs the calculations correctly.

When your program runs, it should match the expected output. Go back in and put in labels as

needed. The program should work for any valid inputs that the user provides.

Write a Python program that manages the student records of a class in your school.

Lists: Create a list of student names. These are strings representing the names of

students in your class $($e$.$g$.,["$John$",$ "Mary", "Peter", "Sam"$]).$

Tuples: For each student, create a tuple that stores their grades in different subjects.

The subjects are Mathematics, English, and Science $($e$.$g$.,(85,90,88)).$

Dictionaries: Now, create a dictionary where the keys are the names of the students

$($from your list$),$ and the values are the tuples storing their grades. This way, you can

easily look up a student's grades in different subjects.

Your final program should be able to print the names of all students, their grades in different

subjects, and their average grade. Make sure to use loops and appropriate Python built$-$in

functions in your program.
