Stripping off the seconds in datetime python

I know it's quite old question, but I haven't found around any really complete answer so far.

There's no need to create a datetime object first and subsequently manipulate it.

dt = datetime.now().replace(second=0, microsecond=0)

will return the desired object

dtwithoutseconds = dt.replace(second=0, microsecond=0)
