Question

Must be done in python and using linux mint

Write a program to create a text file which contains a sequence of test scores. Each score will be between 0 and 100 inclusive. There will be one value per line, with no additional text in the file. Stop adding information to the file when the user enters -1 The program will first ask for a file name and then the scores. Use a sentinel of -1 to indicate the user has finished supplying data A sample session of this part might be Enter data file name: scoresl.txt Enter the scores, enter -1 to quit: Score: 100 Score: 79 Score: 67 Score: 32 Score: -1 After the above session the contents of scores1.txt would be 100 79 32 Create two or more files with test results Part 2: Write a program that will ask the user for a data file. You may use raw_input or a cs160gui method to allow the user to enter a file. Use one of the data files created from part 1. Each line of the file must contain a single value. Fill a list with the values from the file Once the list has been filled with values the program should display, with appropriate labels, the largest values from the list, the smallest value from the list, the average of the list (with 2 places after the decimal point). Then ask the user for a lower limit and an upper limit. Display all the values from the list that fall within that range. The numeric values must be right justified

----------------------------Part1------------------------

filename = input('Enter file name : ')

# open file in write mode

fptr = open(filename, 'w')

print('Enter the scores, enter -1 to quit:')

# infinite loop

while True:

    score = int(input(''))

   

    if score == -1:

   

        break

       

    # write into the file

    fptr.write(str(score) + '\n')

-----------------------------Part2------------------------------

filename = input('Enter file name : ')

# open file in read mode

fptr = open(filename, 'r')

# read the content of file

x = fptr.read()

arr = []

# read file line by line

for y in x.split('\n'):

    arr.append( int( y ) )

   

largest = arr[0]

smallest = arr[0]

sum = arr[0]

for i in range( 1 , len(arr) ):

    if arr[i] > largest:

   

        largest = arr[i]

       

    if arr[i] < smallest:

   

        smallest = arr[i]

       

    sum += arr[i]

   

average = sum / len(arr)

   

print('Largest Score :', largest)

print('Smallest Score :', smallest)

print('Average Score :', average)

l = int(input('\nEnter the lower limit: '))

u = int(input('Enter the upper limit: '))

for i in arr:

    if i >= l and i <= u:

   

        print(i)

Sample Output
