After the 'write' the current position in the file is after the "hello", so 
reading will read further content from there.

The following works (disclaimer: I'm utter newbie in Python, and didn't consult 
the documentation, and it's the first time I've seen the Python 'open'):


f = open("pw", "r+")
f.write( "hello" )
f.seek( 0 )  # Go back to start of file
f.read()
f.close()
