Render external code in markdown

[Vaibhav Vikas]

I am creating Github Pages to render my code.

To show code block in Markdown ~> we use

```python

# Our Code Here

``` 

My objective is.

I have an external file stored somewhere say /code/py_script.py

Now, I want to render it in the same way.

I want is to have 

```python

My code from /code/py_script.py is rendered here without copying it here.

```
