Call python script from ruby

Question

For example, I can use Python scripts in PHP like there:

exec("python script.py params",$result);

where "script.py" - script name and variable $result save output data.

How I can make it with Ruby? I mean, call Python scripts from Ruby.

Answer 1

You can shell-out to any shell binary and capture the response with backticks:

result = `python script.py params`

Answer 2

One way would be exec.

result = exec("python script.py params")

Answer 3

Another way to do the same thing would be,

system 'python script.py', params1, params2

Answer 4

I used the following python call from a ruby module.

In my case using exec() didn't work because it interrupts the current process and caused the simulation I was running to fail.

# run python script
`python #{py_path_py} #{html_path_py} #{write_path_py}`
