Question

Specification

The script must define 4 functions

random_number_file_create

lines_print

lines_count

total_numbers_in_file

random_number_file_create

This functions must have the following header

This function must create a file where each line has a pseudorandom number.
Each of these numbers must between the values of the parameters min and max.
The name of the file is given by the parameter filename.
The number of lines in the file is given by the parameter entries.
The function must close the file after it has written all the values.

lines_print

This functions must have the following header

This function must print each line of the file.
There should be no blank lines between the lines of the file.
The function must close the file after it has printed all the lines.

lines_count

This functions must have the following header

This function must count the number of lines in the file and return that total.
The function must close the file after it has read all the lines.

total_numbers_in_file

This functions must have the following header

This function must calculate the total of all the numbers in the file and return that total.
The function must close the file after it has read all the lines.

Run code

At the bottom of the script you must have the following code

The code above will run the functions you create, and make it easier for me to score this assignment.

Testing

When you run your script the output should look exactly like this

Explanation / Answer

import random

def random_number_file_create(min, max, filename, entries):
   randfile = open(filename, "w" )

   for i in range(entries):
       line = str(random.randint(min, max)) + " "
       randfile.write(line)
   randfile.close()

def lines_print(filename):
   f = open(filename, "r")
   for line in f.readlines():
       print line
   f.close()

def lines_count(filename):
   f = open(filename, "r")
   count = 0
   for line in f.readlines():
       count = count + 1
   return count
   f.close()

def total_numbers_in_file(filename):
   distances = []
   with open(filename, 'r') as f:
       for line in f:
           if line[0].isdigit():
               distances.extend(line.splitlines())
  
   L = [int(n) for n in distances if n]
   total = sum (L)
   return total

FILENAME = "numbers.txt"
random.seed(83)
random_number_file_create(50, 100, FILENAME, 20)
lines_print(FILENAME)
print()
entries = lines_count(FILENAME)
total = total_numbers_in_file(FILENAME)
average = round(total/entries)
print("Entries:", entries)
print("Total:", total)
print("Average:", average)
