It doesn't matter. You can use try...finally as well in Python 2.4.
It's just not possible to use except and finally clauses in one
statement such as:
try:
1/0
except ZeroDivisionError:
print "incident!"
finally:
print "cleanup"
However in theory you don't really need finally but you can simulate
it using nested try...except statements:
-----
try:
try:
1/0
try:
print "cleanup"
except Exception:
raise FinallyException( sys.exc_info() )
except ZeroDivisionError:
print "incident!"
try:
print "cleanup"
except Exception:
raise FinallyException( sys.exc_info() )
except Exception:
exc_cls, exc_value, exc_tb = sys.exc_info()
if exc_cls == FinallyException:
fin_exc_cls, fin_exc_value, fin_exc_tb = exc_value[0]
raise fin_exc_cls, fin_exc_value, fin_exc_tb
else:
print "cleanup"
except Exception:
raise FinallyException( sys.exc_info() )
raise exc_cls, exc_value, exc_tb
-------
Note that this expression is regenerated from the above
try...except..finally statement using Py25Lite ( see [1],[2] ) which
is a tool used to provide some Python 2.5 constructs for programmers
working with Python 2.4.
