Line 3. How to Create a datetime object on a certain time
Line 4. How to subtract or add time to another time and how to compare datetime objects
Line 5. How to convert datetime to string
Line 6. How to get the current time

import datetime

lasttime = datetime.datetime(1900,1,1,0,0,0)

while True :
    if lasttime  < datetime.datetime.now() - datetime.timedelta(seconds=30) :
        print("30 Secornds has passed Date Now is :" + datetime.datetime.now().strftime("%A %d %B %Y %I:%M:%S%p") )

Delete files that are older than 10 (or x) days

Here is a simple python script to delete files from the current directory that are older than 10 days,
you probably need to customize it a little to specify the files to delete.


#!/usr/bin/python

# run by crontab
# removes any files in current folder older than days_old days

import os, sys, time

def get_file_directory(file):
    return os.path.dirname(os.path.abspath(file))
    
now = time.time()
days_old = 1 #change this to how many days old files to delete
cutoff = now - (days_old * 86400)
files = os.listdir(get_file_directory(__file__))
file_path = get_file_directory(__file__)
for xfile in files:
        print("Check :" + xfile)
        if xfile.startswith('0000'):    #My Files stated with 0000 you can add other criteria here maybe xfile.endswith('.OLD')
            fullFile = os.path.join(str(file_path), xfile)
            #print("Path : " + fullFile)  Remove the comment to list all the files to be deleted
            if os.path.isfile(fullFile):
                t = os.stat(fullFile)
                c = t.st_ctime
                # delete file if older than [days_old] days
                if c < cutoff:
                    print("Will Remove " +fullFile + "to go ahead and remove the files please remove the # in the next line") #for now we will just print it
                    #os.remove(fullFile)  #comment this line to delete the files
