PyRun_SimpleString problem.

[Arinte]

I am trying to run a python file from a dll.  When I run the file w/
PyRun_AnyFile it works fine.  But, when I try to run the code line by line
w/ PyRun_SimpleString I get this error on function definitions.

def bottle(n):
  File "<string>", line 1
    def bottle(n):
                ^
SyntaxError: unexpected EOF while parsing
    if n == 0: return "no more bottles of beer"
  File "<string>", line 1
    if n == 0: return "no more bottles of beer"

Can I run files line by line if they define functions?  If so, how?

Thanks
