Python built-in function (--vars)

English documents:

vars ([ object])

Return the __dict__ attribute for a module, class, instance, or any other object with a __dict__ attribute.

Objects such as modules and instances have a updateable __dict__ attribute; however, other Objects could have write restrict Ions on their __dict__ attributes (for example, classes use a dictproxy to prevent direct dictionary updates).

Without an argument, vars() acts locals() . Note, the locals dictionary is only useful for reads since updates to the locals dictionary is ignored.

Description

1. When a function does not receive a parameter, its function, like the locals function, returns a local variable within the current scope.

2. When a function receives a parameter, the parameter can be a module, class, class instance, or an object that defines the __dict__ property.
