Question

how to creat Create a text file that contains a list of integer numbers separated by comma (numbers.txt). E.g. 3, 7, 5, 1, 11, 8,2, 6 2- how to Write a python program (minMax.py) to read the file numbers.txt and find the largest and smallest numbers in the file. (without using use min(), max()). calculate the average and output the results. 3-Use python file i/o, write a python program (fileCopy.py) that makes a copy of minMax.py (Read contents of minMax.cp and save it to minMaxCopy .py) so that each time when the program is run, a different copy is created. You may want to use datetime module to get the current time. E.g. minMaxCopy20201009072003.py was created on 10/09/2020 3seconds past 7:20

Text format:

import sys
f = open('numbers.txt')

min = sys.maxsize
max = -sys.maxsize-1
sum = 0
n = 0
while True:
    line = f.readline()
    if line == '':
        break
    ls = line.split(',')
    for i in range(len(ls)):
        x = int(ls[i].replace(' ', '').replace('\n', ''))
        if x < min:
            min = x
        if x > max:
            max = x
        sum += x
        n+=1
print("Smallest number:", min)
print("Largest number:", max)
print("Average:", float(sum)/n)

Output:

Text format:

import datetime

now = datetime.datetime.now()
f1 = open('minMax.py')
filename = 'minMaxCopy' + str(now.year) + str(now.month) + str(now.day) + str(now.hour) +\
           str(now.minute) + str(now.second) + '.py'
f2 = open(filename, 'w')
ls = f1.readlines()
for i in ls:
    f2.write(i)
f2.close()
