Why am I getting an error message in Python 'cannot import name NoneType'? -
i'm trying convert code 2 3 , following simple script
import types types import nonetype
results in
importerror: cannot import name nonetype
how can convert above 2 3?
there no longer nonetype
reference in types
modules. should check identity none
directly, i.e. obj none
. alternative way, if need nonetype
, using:
nonetype = type(none)
this exact same way types.nonetype
defined, before removed on november 28th, 2007.
as side note, not need import module able use from .. import
syntax, can drop import types
line if don’t use module reference anywhere else.
