Newbie: print-to-file-Syntax

[Sabine Richter]

Hello,

I looked the syntax up in the python doc, but nevertheless, I don't
understand it. What's wrong?

PROT=open("c:\\existing_dir\\prot.txt",'w')
PROT.write("Written String") 
print >> PROT "Printed String"
print PROT "Printed String"

PROT.close()

--> Written String has been written. But for the print-Statements I get
a syntax error message 


And a second question: 

Is it possible to write:
PROT=None
print... print-to-file-syntax

Later, I want to print to file, but now I want to print to STDOUT.
The doc says: If the first expression evaluates to None, then sys.stdout
is used as the file for output. 


Thanks in advance
Sabine
