Call Python functions from TCL script with arguments

I have a Python script, say, sample.py with 2 functions func1() and func2():

def func1():
    print("Called Function 1")

def func2():
    print("Called Function 2")

How do I call this function func2() from the Tcl script and also how to pass the arguments to that function?

The best method is probably to see if tclpython will work for you. (Download links on http://jfontain.free.fr/; pick the one(s) you need.) That should let you write code like this:

# Set up a python interpreter
package require tclpython
set py [python::interp new]

# Load a file in with your definitions
$py exec {
    # This is Python code, embedded directly in Tcl
    evalfile("sample.py")
}

# Evaluate a python expression (in this case, call an argument-less function)
set result [$py eval func2()]

# Dispose of the python interpreter
python::interp delete $py

python code needs this (I called it junk.py and put it in the same folder with tcl script).

import sys

def func1():
    print("Called Function 1")

def func2():
    print("Called Function 2")

if __name__ == '__main__':
    eval(sys.argv[1] + '()')

Tcl file called test_tcl.tcl:

set out [exec python junk.py [lindex $argv 0]]
puts $out

Execute from command line:

tclsh test_tcl.tcl func1

Output is:

Called Function 1
