Different types of string formatting eg %s %i in python Shows how to format time stamp data in python using, type formatting print (datetime.datetime.now().day) TNOW = datetime.datetime.now() print (TNOW.day) print (TNOW.month) print (TNOW.year) print (TNOW.hour) print (TNOW.minute) print (TNOW.second) TNOW = datetime.datetime.now() print (str(TNOW.day) +'-'+str(TNOW.month)+'-'+str(TNOW.year)+'_'+ str(TNOW.hour) + '-' +str(TNOW.minute) + '-' + str(TNOW.second) ) print("%.2i-%.2i-%i_%.2i-%.2i-%.2i" % (TNOW.day,TNOW.month,TNOW.year,TNOW.hour,TNOW.minute,TNOW.second)) help() : FORMATTING '{:%d-%m-%Y_%H:%M:%S}'.format(TM) TNOW = datetime.datetime.now() TFORMAT = '{:%d-%m-%Y_%H:%M:%S}'.format(TNOW) print(TFORMAT) DEVICE_ACCESS.send("copy nvram:startup-config scp://[email protected]//data/05_PYTHON_DEMO/ROUTER_" + RTR +"_"+ TFORMAT + "\n\n\n\n") Sample Script import paramiko import time from getpass import getpass import datetime TNOW = datetime.datetime.now().replace(microsecond=0) TFORMAT = '{:%d-%m-%Y_%H:%M:%S}'.format(TNOW) username = 'admin' password = 'admin' scp_pass = getpass( prompt = 'Enter SCP server Password :') DEVICE_LIST = open ('09_devices') for RTR in DEVICE_LIST: RTR = RTR.strip() print ('\n #### Connecting to the device ' + RTR + '####\n' ) SESSION = paramiko.SSHClient() SESSION.set_missing_host_key_policy(paramiko.AutoAddPolicy()) SESSION.connect(RTR,port=22, username=username, password=password, look_for_keys=False, allow_agent=False) DEVICE_ACCESS = SESSION.invoke_shell() DEVICE_ACCESS.send('copy nvram:startup-config scp://[email protected]//data/05_PYTHON_DEMO/ROUTER_' + RTR + '_'+TFORMAT + '\n\n\n\n') time.sleep(5) DEVICE_ACCESS.send(scp_pass +'\n') time.sleep(1) print ('Backup completed for the device ' + RTR + '\n\n') SESSION.close
