+To write something other than a string, it needs to be converted to a
+string first:
+
+\begin{verbatim}
+>>> value = ('the answer', 42)

\code{f.tell()} returns an integer giving the file object's current
position in the file, measured in bytes from the beginning of the
file. To change the file object's position, use
using the beginning of the file as the reference point.
\begin{verbatim}
->>> f=open('/tmp/workfile', 'r+')
+>>> f = open('/tmp/workfile', 'r+')
>>> f.write('0123456789abcdef')
>>> f.seek(5) # Go to the 6th byte in the file
>>> f.read(1)
