I am calling a Python script from TCL.
My requirement is , the Python script should return a list to the TCL. In TCL I should be able to collect the returned list from Python

Below is my TCL script:

#!/usr/bin/env tclsh8.4 

set py_script  /home/user/ret_list.py

puts [exec $py_script]

#set r = exec $py_script
#puts "$r"

Python script:

#!/usr/bin/python

print ("This is python script")

def func(fruits):
     return fruits

fruits = ["mango", "apple"]
func(fruits)

From my TCL script when I am calling the python script by puts [exec $py_script] , it is working. But if I want to collect the return value in below lines which are commented out, it is not working.

Kindly help.

Thanks
