[snip] > Look at open() for comparison. > > >>> open.__text_signature__ > "($module, /, file, mode='r', buffering=-1, encoding=None,\n > errors=None, newline=None, closefd=True, opener=None)" In your comparison example, a forward slash appears again, but this time after "$module" in the location where "obj" previously appeared in the repr example. Is it indicating a similar use here? Can you provide a link to "__text_signature__" in the docs? I tried searching for it, but came up empty. -- boB _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
