File45. Даны три файла одного и того же типа, но разного размера. Заменить содержимое самого короткого файла на содержимое самого длинного.

Решение на Python 3:

# -*- coding: utf-8 -*-
import random
import sys
import os
from shutil import copyfile

file1 = "file45_1.txt"
file2 = "file45_2.txt"
file3 = "file45_3.txt"

try:
    size1 = os.stat(file1).st_size
    size2 = os.stat(file2).st_size
    size3 = os.stat(file3).st_size

    min_size = size1
    min_file = file1
    max_size = size1
    max_file = file1

    if size2 < min_size:
        min_size = size2
        min_file = file2
    
    if size3 < min_size:
        min_size = size3
        min_file = file3

    if size2 > max_size:
        max_size = size2
        max_file = file2
    
    if size3 > max_size:
        max_size = size3
        max_file = file3

    print("min size: ", min_size)
    print("min file: ", min_file)
    print("max size: ", max_size)
    print("max file: ", max_file)
    ## copyfile(source, destination)
    copyfile(max_file, min_file)

except:
    print("Error: ", sys.exc_info())
