This won't work. It's impossible to know how deep to indent without any 
begin/end-tokens. Consider this simple example:

if foo:
    print "foo"
    if bar:
       print "bar"

is equal to

'if foo:;print"foo";if bar:;print "bar"'

But that could as well be

if foo:
    print "foo"
if bar:
    print "bar"

So - you need some block delimiters.

And as it has been said to you a bazzillion times: stop doing what 
you're doing. Use python. As it is. Your limited understandig of parsing 
and language design makes your task beyond your capabilites. For now. 
And the forseeable future...
