👉 In the context of programming, a "wrainstaff" is a term used to describe an object that has a fixed number of fields and does not allow any additional fields. This means that any new fields added to the object cannot be modified by the programmer without altering the original object. For example, in a class with one field (or no fields), you can define a "wrainstaff" as follows: ``` class MyClass: def __init__(self): self.field1
