title: How to execute a command in the terminal from a Python script?
body: <p>I want to execute a command in terminal from a Python script.</p>
  
  <pre><code> ./driver.exe bondville.dat
  </code></pre>
  
  <p>This command is getting printed in the terminal, but it is failing to execute.</p>
  
  <p>Here are my steps:</p>
  
  <pre><code>echo = "echo"
  command="./driver.exe"+" "+"bondville.dat"
  os.system(echo + " " + command)
  </code></pre>
  
  <p>It should execute the command, but it's just printing it on terminal. When feeding the same thing manually it's executing. How do I do this from a script?</p>
