[Answer]-Auto close a file opened in django __init__.py

When you terminate the Django development server with Ctrl+C, this will kill the associated Python process and thus close all opened files.

To check this behavior, you can make the following test:

1. Start a Python interpreter and open a file:

   open('all_india_pin_code.csv')

2. In a shell, check that the file was opened by your Python process:

   $ lsof | grep all_india_pin_code.csv

   This will return you a result like:

   python 26395 user 3r REG 254,2 0 12217876 all_india_pin_code.csv

3. Then kill the Python interpreter. For example:

   $ kill -9 26395

4. Check again if the file is opened. This command will return no result, because the file has been closed:

   $ lsof | grep all_india_pin_code.csv
