Thanks everybody , and especially Chris - i used split and it took me 15
mins to make it work :)

The final version looks like:

from datetime import datetime, date, time
today_day = datetime.now()
time_tuple= today_day.timetuple()
hhh = open("file_with_data.data",'r')
for nnn in hhh:
    if nnn.split()[2] == str(time_tuple[1]).strip(' \t\n\r')   and
nnn.split()[4]  == str(time_tuple[0]).strip(' \t\n\r') and  nnn.split()[3]
== str(time_tuple[2]).strip(' \t\n\r')   :
             print nnn

Cheers and good day everyone
Yuri
