How to extract the value of a specific key, and add it to a variable using Python?

Question

I have a site that takes an userinput eg USD and requests data from an API to get exchange rates. I assign to a variable, var = {'rates': {'DKK': 7.4618}, 'base': 'EUR', 'date': '2020-05-06'} and want to extract only the specific key (DKK) and it's value to their own variable.

Answer 1

If your data format is the same as above then you can access in the following way.

DKK = var.get("rates", {}).get('DKK')

Answer 2

You can access a dictionaries value by passing the key to the dict.

value = var['rates']['DKK']
