Question

Write a program that loads a list of integers from a file. The file is called numbers.dat and it contains one integer per line. Write the program, complete with validation and exception handling, that displays the high value, low value, total number of values and the average. While it is possible to do this without using a list, I am requiring you to load the numbers (valid only) into a list and THEN process the data. You may use the built-in functions and methods available for lists.

Create your own data file.

Sample run if the file exists and contains 9 valid data items

>>>

9 items in the list

Lowest value: 1

Highest value: 12

Average: 6.0

Sample run if the file does not exits

>>>

error opening file

The file exits, but is emtpy

>>>

0 items in the list

No data in the list

Sample run if the file exists and contains 3 data items, 2 of which are not valid. Program ignores invalid data and proceeds.

>>>

error in value, not added

error in value, not added

1 items in the list

Lowest value: 12

Highest value: 12

Average: 12.0

PLEASE DO IT IN PYTHON PLEASE!

Explanation / Answer

import numpy in np
def readFile():
   arr = []
   inp = open ("number.dat","r")
   #read line into array
   for line in inp.readlines():
       if isinstance( line, int )
           arr.append(line)
       else
           print "error in value, not added"
   print "Lowest value:" + min(arr)
   print "Highest value:" + max(arr)
   print "Average value:" + np.average(arr)
