I tend to use isinstance to work out what kind of AST node I'm looking
at, although I often use the visitor infrastructure to avoid doing
even that.

A quick style tip here: it's easier to iterate over the nodes, and if
you want a counter, use the enumerate built-in function. Together with
the above advice...
for count, func in enumerate(parse_file.node.nodes):
if isinstance(func, compiler.ast.CallFunc):
...

Take a look at the help text for enumerate to see how I arrived at the
above:
help(enumerate)
