Is it possible only to declare a variable without assigning any value in Python?

Question

Is it possible to declare a variable in Python, like so?:

var

so that it initialized to None? It seems like Python allows this, but as soon as you access it, it crashes. Is this possible? If not, why?

Answer 1

As we know Python is dynamic, so you here you do not need to declare things because they exist automatically in the first scope where they're assigned. So, all you need to do is use a regular old assignment statement as above.
