Question

USE BASIC PYTHON

Focus on Basic file operations, exception handling.

Save a copy of the file module6data.txt (Below)

Write a program that will

a. Open the file module6data.txt

b. Create a second file named processed. txt

c. Read the numbers from the first file one at a time. For each number write into second file, if possible, its

I. Square

ii. Square root

iii. Reciprocal (1/number)use a math module function for the square root. use exception handling to trap possible errors.

d. Report the number of items in the original file and the number that were successfully stored in the second file.

e. Report the number of each type of error: ValueError, ZeroDivisionError, TypeError

• Use meaningful variable names.  Single letter variable names are forbidden except as counters in loops.
• Use blank lines to separate major parts of a program or function.
• Use spaces around all operators. For example, write x = y + 5, NOT x=y+5
• Use named constants, not magic numbers.  
• Organize your python program file. Your file should have, in this order
  • a full header comment, as specified in the guidelines
  • any named constants used by the program,
  • the definition of the main() function,
  • all functions other than main(),  
  • the call to main()at the very bottom of the file.

RAW CODE

import math

File = open('module6data.txt', 'r') ### Opening File
Lines = File.readlines() ## Reading file line by line
output = open('processed. txt', 'w') ### Opening new file processed.txt
original_count, processed_count = 0, 0 ### Initializing values to 0
ve,te,zde = 0,0,0
for line in Lines:
        try:
                original_count += 1 ### x += 1 is same as x = x + 1
                square, square_root, reciprocal = int(line) ** 2, math.sqrt(int(line)), 1 / int(line) ## math.sqrt() don't work on negative numbers
                number = int(line)
                output.write("{}: {}, {}, {}\n".format(number, square, square_root, reciprocal)) ## output is saved in format "number: square, square_root, reciprocal" in text file.
                processed_count += 1
        except ValueError: ### Type of error
                ve += 1
        except ZeroDivisionError:
                zde += 1
        except TypeError:
                te += 1

output.close() ### closing file

if __name__ == '__main__': ### main function.
        print("Number of items in the original file: ",original_count) ### Reporting results
        print("Number of items in the processed file: ",processed_count)

        print("Number of TypeError: ",te)
        print("Number of ValueError: ",ve)
        print("Number of ZeroDivisionError: ",zde)
