...n-time, as well.

}
This is possible because N, being constant and initialized at decla...

Accessing class variables from a list comprehension in the class definition
... scope, regardless of Python version. That would be the expression for the outermost iterable. In your example, it's the range(1):
y = [x for i in range(1)]
