After shutting down computer how to reactivate a django server
'm very new to django web development in python and I'm currently following a course on building a simple django website. The problem is, I went to sleep and decided to shut down my computer. After sometime I need to reactivate the website or something because the website just says 'This site can't be reached'. I opened up the code and I'm not sure if I'm suppose to write a certain command in the terminal or something. The terminal is empty when before it was running the website and had stuff there. I do understand that it is going to stop running the website when I shut down my computer because it's my computer hosting it, but I just need to know how to start running it again. So how do I 're-activate' a django website? -

I am running last 6 months of report which contains month, visits, fees and other fees as fields. When a month not having any visits its shows empty query set. how to pass a value to empty query set. I am getting result as below: <QuerySet [{'month': 7, 'visits': 19, 'fees1': Decimal('6380'), 'other_fees': Decimal('1730')}]> <QuerySet [{'month': 6, 'visits': 6, 'fees1': Decimal('3201'), 'other_fees': Decimal('851')}]> <QuerySet [{'month': 5, 'visits': 6, 'fees1': Decimal('900'), 'other_fees': Decimal('1685')}]> <QuerySet []> <QuerySet [{'month': 3, 'visits': 2, 'fees1': Decimal('455'), 'other_fees': Decimal('605')}]> <QuerySet [{'month': 2, 'visits': 2, 'fees1': Decimal('430'), 'other_fees': Decimal('504')}]> month 4 is not having any visit and fees since, the query set being empty. instead of empty. I want to set value of 0 for the fields.
