What’s the scope of a variable initialized in an if statement?

by

Python variables are scoped to the innermost function, class, or module in which they’re assigned. Control blocks like if and while blocks don’t count, so a variable assigned inside an if is still scoped to a function, class, or module.

(Implicit functions defined by a generator expression or list/set/dict comprehension do count, as do lambda expressions. You can’t stuff an assignment statement into any of those, but lambda parameters and for clause targets are implicit assignment.)
