Formatargspec Warning in import line

[nvenkat94]

We still facing that inspect has no attribute "Formatargspec". I think you were didn't consider about that.
I have changed that formatargspec into signature which was mentioning below.
Earlier Syntax Like This:

signature = inspect.formatargspec(regargs, varargs, varkwargs, defaults,
                                      formatvalue=lambda value: "")[1:-1]

Now Modified Like This:

signature = inspect.signature(regargs, varargs, varkwargs, defaults,
                                      formatvalue=lambda value: "")[1:-1]

Now there is no error while executing. But I want make sure is it right. Pls try to fix this issue in coming version.
I'm using nltk V3.8.1.
python V 3.8.
I think formatargspec has been deprecated Before 4 or 5years. But Still you are not fix that issue.
