Here's how it looks here:

>>> y = 1900
>>> leap = "no"
>>> if y % 400 == 0 :
...  leap = "yes"
... elif y % 100 == 0 :
...  leap = "no"
... 
>>> leap
'no'
>>> 

When you hit enter after the first ':', interpreter should print three
dots to indicate that you're entering a block.. or what's it called.
Anyway, I'm not quite sure what's wrong on your end but note that by
convention, you shouldn't leave a space before the ':'. It don't cause
an error but this is a matter of good style..
