total = 0
month = raw_input('Print the current month in all underscore: ')
day = input('Print dya of the month with integers: ')
try:
number = int(day)
except ValueError:
print(day, "is not an integer.")
else:
if month == "january":
total + day
print month, day, 'is the day #', total
elif month == "february":
total = 31 + day
print month, day, 'is the day #', total
else:
print 'you misspelled the month'


why doesn't this check is the day input is integer or not. it just crashes. WTF

This is a very stupid question I'm sure but I just need to know. The Photoelectric Effect shows that when light with a high enough frequency hits a metal that electrons can be emitted and when light hits a gas photons are emitted. So can photons also be emitted from a metal and vice versa for a gas?
