The doc of `itertools.filterfalse()` shows `predicate` argument but the docstring shows `function` argument

The doc of itertools.filterfalse() shows predicate argument as shown below:

itertools.filterfalse(predicate, iterable)

But the docstring of itertools.filterfalse() shows function argument instead of predicate argument as shown below:

from itertools import filterfalse

print(help(filterfalse))
# class filterfalse(builtins.object)
#  |  filterfalse(function, iterable, /)
# ...

So the docstring of itertools.filterfalse() should show predicate argument instead of function argument for consistency as shown below:

from itertools import filterfalse

print(help(filterfalse))
# class filterfalse(builtins.object)
#  |  filterfalse(predicate, iterable, /)
# ...

In addition, both the doc and docstring of itertools.takewhile() properly show predicate argument as shown below:

itertools.takewhile(predicate, iterable)

from itertools import takewhile

print(help(takewhile))
# class takewhile(builtins.object)
#  |  takewhile(predicate, iterable, /)
#  ...

And, both the doc and docstring of itertools.dropwhile() properly show predicate argument as shown below:

itertools.dropwhile(predicate, iterable)

from itertools import dropwhile

print(help(dropwhile))
# class dropwhile(builtins.object)
#  |  dropwhile(predicate, iterable, /)
# ...
