Hello,

Thanks for everything previously, but just to I ask about code
indentation,this with { and } doesn't
employed, here is my example how can I solve this about code
indentation:

>>> n=90
>>> if n==90:
        {print "bok kjai ma'}
  File "<input>", line 2
    {print "bok kjai ma'}
         ^
SyntaxError: invalid syntax

 
Thanks!!!!!!!
 
Regards,Vedran
