Question

The file unsorted_fruits.txt (which is available in the resources section of this unit in the resources section) contains a list of 26 fruits, each one with a name that begins with a different letter of the alphabet. Write a program named sort_fruits.py that reads in the fruits from the file unsorted_fruits.txt and writes them out in alphabetical order to a file named sorted_fruits.txt. For this assignment you must incorporate the use of a list, for loop and / or while loop. For this assignment you must create either pseudo code or a flowchart of your program and attach it along with your assignment submission. You model must show how your program will read the input file, sort the entries and generate the output file. In addition, you must submit both your program source code sort_fruits.py as well as the sorted file sorted_fruits.txt with your assignment.

Answer 1

Here you go:

infile = open("unsorted_fruits.txt", "r")

lines = infile.read().splitlines()

i = 0

while i < len(lines)-1:

   if lines[i+1] < lines[i]:

       tmp = lines[i]

       lines[i] = lines[i+1]

       lines[i+1] = tmp

       if i > 0:

           i -= 1

   else:

       i += 1

outfile = open("sorted_fruits.txt", "w")

outfile.write('\n'.join(lines) + '\n')

Answer 2

Answer:

For the given problem, prompts the user to open the unsorted text file in read mode and unsorted file in write mode. Read the lines of unsorted file and store them in a list namely fruits. After this, sort the list using sort() function. Now, check the blank lines and write them in sorted text file. In the last, close both the unsorted and sorted file.

Further Explanation:

Code: Following is the python code that reads the fruits from "unsorted_fruits.txt" and writes in alphabetical order in the file "sorted_fruits.txt".

#open the unsorted file in read mode

inputfile = open("unsorted_fruits.txt", "r")  

#open the sorted file in write mode

outputfile=open("sorted_fruits.txt","w")

#reading the lines of input file and store them in a list

fruits = inputfile.readlines()  

#sort the list that contains fruits

fruits.sort()

#first remove the blank lines and write into the output file

For fruit in fruits:

If fruit != ”\n”

outputfile.write(fruit)

#close the input file

inputfile.close()

#close the output file

outputfile.close()
