Hi,
Is this the correct way to handle a ValueError exception and should I
get in the practice of catching them? Also any suggestions on the program.
thanks

Might help if I included the program :)
#!/usr/bin/python
import time
print "Enter year as 0000"
print "Enter month and day as 00"
while True:
try:
yr = int(raw_input("What year were you born? "))
mn = int(raw_input("What month were you born? "))
dy = int(raw_input("What day were you born? "))
curr_date = time.strftime("%Y %m %d", time.gmtime())
ynum = int(time.strftime("%Y", time.gmtime())) - int(yr)
mnum = int(time.strftime("%m", time.gmtime()))
dnum = int(time.strftime("%d", time.gmtime()))
mn = int(mn)
dy = int(dy)
if mn - mnum:
print "You are %i" % ynum, "years old."
break
elif mn == mnum and dy < dnum:
print "You are %i" % ynum, "years old."
break
else:
ret = int(ynum) - 1
print "You are %i" % ret, "years old."
break
except ValueError:
print "Oops, You must enter a number!"
