title: Execute cmd from same directory with commands in python
body: <p>I have a folder named Scripts in which I have  files. Namely test.py and ffmpeg.exe 
  Now, I want to write a code in test.py to execute this ffmpeg.exe in same directory with some arguments/commands.</p>
  
  <p>I looked it up, but, only found how to execute cmd with arguments. I don't want to call cmd and then change directory and execute this command.</p>
  
  <p>Any other way for this?</p>
