I have tried following the Go Docs in order to call a python script which just outputs "Hello" from GO, but have failed until now.
exec.Command("script.py")
or I've also tried calling a shell script which simply calls the python script, but also failed:
exec.Command("job.sh")
Any ideas how would I achieve this?
EDIT
I solved following the suggestion in the comments and adding the full path to exec.Command().
Python can get embedded as a shared library into programs written in other languages. Here's a trivial example for executing Python code in a Golang program and exchanging data between the two runtimes.
To run Python scripts with the python command, you need to open a command-line and type in the word python , or python3 if you have both versions, followed by the path to your script, just like this: $ python3 hello.py Hello World! If everything works okay, after you press Enter , you'll see the phrase Hello World!
To run the app outside of the VS Code debugger, use the following steps from a terminal: Set an environment variable for FLASK_APP . On Linux and macOS, use export set FLASK_APP=webapp ; on Windows use set FLASK_APP=webapp . Navigate into the hello_app folder, then launch the program using python -m flask run .
Did you try adding Run()
or Output()
, as in:
exec.Command("script.py").Run()
exec.Command("job.sh").Run()
You can see it used in "How to execute a simple Windows DOS command in Golang?" (for Windows, but the same idea applies for Unix)
c := exec.Command("job.sh")
if err := c.Run(); err != nil {
fmt.Println("Error: ", err)
}
Or, with Output()
as in "Exec a shell command in Go":
cmd := exec.Command("job.sh")
out, err := cmd.Output()
if err != nil {
println(err.Error())
return
}
fmt.Println(string(out))
