In general you can't run code for one language in a
program written in another language. (There are a few
exceptions, usually where one language is written in
the other).

The nearest you can usually get is to execute the
Tcl program using the tcl interpreter (tclsh) from
the OS using a module like subprocess.

However, Tcl and Python do have a connection  via
the Tkinter module and you can call tcl code
using Tkinter like so(Python v3):

import tkinter
tcl = tkinter.Tcl()
tcl.eval("""
puts [expr 4+5]  # or any other arbitrary tcl
""")

So to execute a Tcl file you can read the contents
into a string and then execute that string. Note that
the return value will always be a string.
