I've just replaced my bash script with a Python script, and this is my first script where I used class.Please review and give me suggestions.#!/usr/bin/env python# This Script will compress One day old file means yesterday filesfrom __future__ import print_functionimport osimport sysimport timeimport globimport subprocessfrom datetime import datetimenday = 1        # set how many days old fileftype = *.log     # set file type which should be compressedlookinto = /var/log/  # path of filesclass CheckFile(object):    'Operation on file like get size,file time etc..'    def __init__(self,fname):        self.fname = fname    def size(self):        'print size in bytes MB'        num = os.path.getsize(self.fname)        for s in [ 'bytes','KB','MB','GB','TB' ]:            if num < 1024.0:                return %3.1f %s % (num,s)             num /= 1024.0    def date(self):        'print file date'        self.unix_time = os.path.getmtime(self.fname)        self.file_date = datetime.fromtimestamp(self.unix_time)        return self.file_date.strftime('%d/%m/%y')    def days_of_days_old(self):        'print how much file is old from today'        self.date()        days = (datetime.today() - self.file_date).days        return days def compresse_file(file):    print(Compressing...)    cmd = gzip -v  + file    os.system(cmd)if __name__ == '__main__':    os.chdir(lookinto)    print('{0:10}{1:10}{2:10}'.format(Size,Date,File Name))    print('{0:10}{1:10}{2:10}'.format(-----,------,---------))    for file in glob.glob(ftype):        f = CheckFile(file)        if f.days_of_days_old() == nday:            print('{0:10}{1:10}{2:10}'.format(f.size(),f.date(),f.fname))            compresse_file(file)            print(file status after compressesion)            f = CheckFile(file + .gz)            print('{0:10}{1:10}{2:10}'.format(f.size(),f.date(),f.fname))            print()
