That is not a Python error, that's a complaint of your shell.
If you make a Python script executable you also have to insert the proper 
hash-bang line. In the case of Python 2

#!/usr/bin/python2

will probably work. Example shell session:

$ cat tmp.py
def  demo():
    print "heureka"

demo()
$ ./tmp.py
./tmp.py: line 1: syntax error near unexpected token `('
./tmp.py: line 1: `def  demo():'
$ cat tmp2.py
#!/usr/bin/python2

def  demo():
    print "heureka"

demo()
$ ./tmp2.py
heureka
$
