如何从Tcl脚本调用Python函数

Question

I have a Python script, say pyscr.py . Let's say this file defines the following function:

def f1() :
    print ('python func executing')

How do I call this function f1 from a Tcl script?

Answer 1

You need to write a Tcl script to define a procedure to execute a Python script, and then call the procedure. Try this:

#! /usr/bin/tclsh
proc call_python {} {
    set output [exec python pyscr.py]
    puts $output
}

call_python
