Why can not catch the inner exception

[=?gb2312?B?yMvR1MLkyNXKx8zs0cSjrM37vKvM7NHEsru8+7z]

Please see the follow code, I can not catch the exception " IOError"
raised from shutil.copyfile() , why?
try:
if (DEST_TYPE & TYPE_FTP):
fn = oname
ftpc.UploadFile(f, fn)
else:
fn = os.path.join(dst, oname)
shutil.copyfile(f, fn)

.... other code....

except [IOError, FtpcException],why:
num = 0
print >>sys.stderr, "can not copy '%s' to '%s':
%s"%(f, fn, why)
ERR_NUM += 1

I must do like this:
try:
if (DEST_TYPE & TYPE_FTP):
fn = oname
ftpc.UploadFile(f, fn)
else:
fn = os.path.join(dst, oname)
try:
shutil.copyfile(f, fn)
except IOError:
....

.... other code....

except [IOError, FtpcException],why:
num = 0
print >>sys.stderr, "can not copy '%s' to '%s':
%s"%(f, fn, why)
ERR_NUM += 1

Thanks!

ÄãºÃ,

Use a tuple (IOError,FtpcException) instead of a list in the except
statement and it works.
