bash read stdin and pass arguments in pipe code example

Example 1: python execute shell command and get output

import subprocess
process = subprocess.Popen(['echo', 'More output'],
                     stdout=subprocess.PIPE, 
                     stderr=subprocess.PIPE)
stdout, stderr = process.communicate()
stdout, stderr

Example 2: how to read from stdin rust

use std::io;

let mut input = String::new();
match io::stdin().read_line(&mut input) {
    Ok(n) => {
        println!("{} bytes read", n);
        println!("{}", input);
    }
    Err(error) => println!("error: {}", error),
}Run
