I think the intent of the original code was to check if handle had the
attribute "name", I don't think the attribute "write" was the issue.

So then possibly this based on your suggestion:
try:
    write = handel.write
except AttributeError:
    raise
try:
    name = handel.name
    write("# Report_file: %s\n" % name)
except AttributeError:
    pass
write("########################################\n")
