try/except/else/finally problem

[Ed Jensen]

I'm using:

Python 2.3.2 (#1, Oct 17 2003, 19:06:15) [C] on sunos5


And I'm trying to execute:

#! /usr/bin/env python

try:
f = file('test.txt', 'r')
except IOError:
print 'except'
else:
print 'else'
finally:
print 'finally'


And the results are:

File "./test.py", line 9
finally:
^
SyntaxError: invalid syntax


What am I doing wrong?

Thanks in advance for any help.

You need Python 2.5 for that to work. In older Python versions you have to
nest try...except...else and try...finally.

try:
f = file('test.txt', 'r')
except IOError:
print 'except'
else:
print 'else'
finally:
print 'finally'


And the results are:

File "./test.py", line 9
finally:

SyntaxError: invalid syntax

A finally block isn't allowed to appear together with an except block for
releases previous to 2.5. You need to split your exception handling into
two separate blocks.

Thanks Peter.

Given the code above, can you show me what that would look like? The
nested version, that is.

You're using syntax that is valid under Python 2.5, but invalid in
earlier Python versions.
