This uses the version of Tcl that is used within Python, through Tkinter, so you do not need to install anything else.
Install via:
pip3 install tcl_kernel
python3 -m tcl_kernel.installTo use try one of these:
jupyter notebook- Then select the Tcl option in the 'New' section
jupyter qtconsole --kernel tcljupyter console --kernel tcl
For details of how this works, see the Jupyter docs on wrapper kernels
