The second approach to coding in Python is to use a code editor. Some people prefer an integrated development environment (IDE), but a code editor is often better for learning purposes. Why? Because when you’re learning something new, you want to peel off as many layers of complexity as...
Because the keys need to be hashable, you can’t use mutable objects as dictionary keys.On the other hand, dictionary values can be of any Python type, whether they’re hashable or not. There are literally no restrictions for values. You can use anything as a value in a Python ...
