Now we do understand what mutable & immutable objects in Python are. Let’s go ahead and discuss the combination of these two and explore the possibilities. Let’s discuss, as to how will it behave if you have an immutable object which contains the mutable object(s)? Or vice versa? Let...
1、The Hitchhiker’s Guide to Python Python’s default arguments are evaluatedoncewhen the function is defined, not each time the function is called (like it is in say, Ruby). This means that if you use a mutable default argument and mutate it, youwilland have mutated that object for a...
