Question

Could anyone please help with this Python code assignment?

In this programming assignment you are to create a program called numstat.py that reads a series of integer numbers from a file and determines and displays the following:

The name of the file.

The sum of the numbers.

The count of how many numbers are in the file.

The average of the numbers. The average is the sum of the numbers divided by how many there are.

The maximum value.

The minimum value.

The range of the values. The range is the maximum value minus the minimum value.

The program is to prompt the user for the name of the file that contains the numbers. If an exception occurs trying to open or read the file an error message is to be displayed. The program is not to crash if the file is not found or there is an error reading the file. Use try-except!

The output from the program is to display the information described above using the following strings preceding the values. There is to be a space between the colon and the value.

File name:
Sum:
Count:
Average:
Maximum:
Minimum:
Range:

At the end of one attempt at reading, or a successful read, of a file the user it to be asked if they would like to evaluate another file of numbers. Use the prompt: Would you like to evaluate another file? (y/n) If the user answers y, then the program is to accept input for another file name. If the user answers with anything other than y, the program is to exit.

PYTHON CODE:

# import sys package
import sys

# loop begins
while True:

  
    try:

        # getting filename from the user
        filename=input('Enter the name of the file ')

        # opening the file
        f=open(filename)

        # variable for counting the integers
        c=0

        # variable to store the maximum number
        maxi=-(sys.maxsize)

        # variable to store the minimum number
        mini=sys.maxsize

        # variable to store the total
        total=0

        # variable to store the average
        avg=0.0

        # reading the file
        for line in f:

            # converting the line into integer
            i=int(line.strip())

            # incrementing the count
            c+=1

            # adding the number to the total variable
            total+=i

            # checking for maximum
            if i > maxi:
                maxi=i

            # checking for minimum
            if i < mini:
                mini=i

        # calculating average
        avg=total/c

        # printing the data
        print('File name: %s'% filename)
        print('Sum: %d' % total)
        print('Count: %d' % c)
        print('Average: %.2f' % avg)
        print('Maximum: %d' % maxi)
        print('Minimum: %d' % mini)
        print('Range: %d' % (maxi-mini))

        # closing the file
        f.close()

    except:

        # prints when file not found
        print('File not found')

  
    # getting user choice of continuing or quitting
    choice=input('Would you like to evaluate another file? (y/n) ')

    choice=choice.lower()

    # if the choice is y , then loop continues
    if choice== 'y':
        continue

    #otherwise quits
    else:
        break
