Python program for updating the time by one second

h=int(input("Enter Hours: "))
m=int(input("Enter Minutes: "))
s=int(input("Enter Second: "))
if((h<0)or(m<0)or(s<0)): # hour or minute or seconds can not be -ve number 
 print("invalid data \n");
elif((h>12)or(m>59)or(s>59)): # the extreme boundary condition 
 print("\n invalid time entry \n");
else:
 s += 1    # increase the seconds by one 
if(s>59):
 s=0;      # after increment when s becomes more than 59 minute changes by 1 
 m += 1
if(m>59):
 m=0
 h += 1
if(h>12):
 h=1;
 print("Time updated by one second is \n",h, m, s);

    Output 1:
            Enter Hours: 12
            Enter Minutes: 59
            Enter Second: 59
            Time updated by one second is 
             1 0 0
    Output 2:
            Enter Hours: -2
            Enter Minutes: 4
            Enter Second: 8
            invalid data
    Output 3:
            Enter Hours: 2
            Enter Minutes: 59
            Enter Second: 65
            invalid time entry
