Example 6.3. Opening a File

 >>> f = open("/music/_singles/kairo.mp3", "rb")
 >>> f
<open file '/music/_singles/kairo.mp3', mode 'rb' at 010E3988>
 >>> f.mode
'rb'
 >>> f.name
'/music/_singles/kairo.mp3'

Example 6.7. Writing to Files

 >>> logfile = open('test.log', 'w')
 >>> logfile.write('test succeeded')
 >>> logfile.close()
 >>> print file('test.log').read()
test succeeded
 >>> logfile = open('test.log', 'a')
 >>> logfile.write('line 2')
 >>> logfile.close()
 >>> print file('test.log').read()
test succeededline 2

Where is the usage of concat?
