Python : Typeerror : Non-empty format string passed to object.__format__

Question

I know this question has been asked here but the solution does not work for me. I am using python 3.4.

I have the following formatting in my script :

Answer 1

One of your parameters is a type that doesn't have their own __format__() method, so object.__format__() is used instead.

object.__format__() doesn't support any formatting options, including field widths and alignment, which is why you get the error.

Conversion to string first should help, but you do need to put your conversion after the field name; instead of {!s4:11s} use {4!s:11s}, etc:

print ( "\t {0:20} {1:<11} {2:<25} {3:11} {4!s:11s} {5!s:>32s}".format(
    files.name.split('/')[-1], sizeof_fmt(files.size),                                                                           
    str(formatted_timestamp), files.owner,
    files.version_id, files.etag))
