Question 1

True or false: The `global` keyword is required to modify a variable defined outside a function.

Accepted Answer

True. Without `global`, assigning to a variable inside a function creates a local variable instead of modifying the outer one.

Question 2

True or false: The `is` operator in Python checks if two variables reference the same object in memory.

Accepted Answer

True. `is` compares identity, not equality; it's often used with `None` because `None` is a singleton.

Question 3

True or false: You can assign an attribute to a Python function object, like `my_func.custom_data = 42`.

Accepted Answer

True. Functions are first-class objects in Python, so you can attach arbitrary attributes to them just like any object.

Question 4

True or false: Python's `and` operator returns a boolean `True` or `False` regardless of operand types.

Accepted Answer

False. `and` returns the first falsy operand or the last operand if all are truthy, not necessarily a boolean.

Question 5

True or false: Python's `list` type uses a linked list data structure internally.

Accepted Answer

False. Python lists are implemented as dynamic arrays (contiguous memory), not linked lists, allowing fast indexing.

Question 6

True or false: Python's `print` function always flushes output to the terminal immediately.

Accepted Answer

False. By default, `print` buffers output; it flushes only when the buffer is full or a newline is printed (in interactive mode).

Question 7

True or false: Python's `else` clause on loops runs only if the loop completed without hitting `break`.

Accepted Answer

True. The `else` block executes after a `for` or `while` loop finishes normally, but not if exited via `break`.

Question 8

True or false: Python's `__init__` method is actually a constructor that creates the object in memory.

Accepted Answer

False. `__init__` initializes an object after it's created; `__new__` is the true constructor that allocates memory.
