I have installed Python 3.9 alfa 0 from spurce code
But I got this error message:

Error:
programmer@crea:~/github/cpython$ python3.8 
Python 3.8.0a0 (heads/master:a323cdcb33, Oct 21 2018, 18:23:54)

>>> import tkinter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.8/tkinter/__init__.py", line 36, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'

I compiled this parameters and
./configure --with-tcltk-includes='-I/opt/ActiveTcl-8.6/include' --with-tcltk-libs='-L/opt/ActiveTcl-8.6/lib/' --with-pydebug

then

make
make test
sudo make install

3.9? current release is 3.7.0
so you are using an unstable version
