title: How to use postman for simple add function in python
body: <p>I am very new to python. </p>
  
  <p>Recently I heard about API, REST and Postman.</p>
  
  <p>I have seen using postman we can send parameters to the function and that functions will return back something.</p>
  
  <p>I thought I will write a simple python function to add numbers.</p>
  
  <p>This will be the code:</p>
  
  <pre><code>def addme(a,b):
      c = a + b
      return c
  </code></pre>
  
  <p>For this simple pure python function how can I handle postman requests and response.</p>
  
  <p>I tried to directly call(POST) this function in postman with its location and giving two parameters in body header. but it won't work.</p>
  
  <p>When I observed it may postman only run for programs which run on some port. So can anybody help me in understanding how to handle all the scenes for this very basic function.</p>
  
  <p>I am really curious to learn from everyone at StackOverflow. And also suggest any efforts to take on this.</p>
