Interactive mode under DOS?

[huisky]

Hi,

I'm trying to use the interactive mode under DOS for Python 2.7. As a
newbie, I do NOT know what is the following problem:

>>>world_is_flat=1
>>>if world_is_flat:
. . . print "be carefule to be not fall out!"
    File "<stdin>", line 2
      print "be carefule to be not fall out!"
              ^
IndenatationError : expected an idented block
>>>

Enybody knows how to fix this simple issue?

regards
