In the interpreter this doesn't work:
f = open(r"c:\python24\image.dat")
line = f.readline()
while line:
... line = f.readline()
... f.close()
Traceback ( File "<interactive input>", line 3
f.close()
^
SyntaxError: invalid syntax
But this does:
f = open(r"c:\python24\image.dat")
line = f.readline()
while line:
... line = f.readline()
...
f.close()
Note the differing placement of the f.close() statement, it's not part of
the while.

Can you copy/paste the actual console transcript?
BTW a better way to write this is
f = open(...)
for line in f:
print line,
f.close()
