In the context of pure functions as taught in "The Complete Python Pure Functions Course 2026," what is the primary characteristic that distinguishes a pure function from a non-pure function when considering side effects?

A pure function always returns a value, whereas a non-pure function might not.

A pure function is guaranteed to be faster than a non-pure function due to its simplicity.

A pure function can modify global variables, while a non-pure function cannot.

A pure function's output depends solely on its input arguments and it has no observable side effects.

Q2Domain Verified

Consider a Python function designed to calculate the factorial of a number. Which of the following implementations, if any, would be considered a pure function according to the principles of "The Complete Python Pure Functions Course 2026," assuming `n` is a non-negative integer?

```python global_sum = 0 def factorial_impure(n): global global_sum if n == 0: result = 1 else: result = n * factorial_impure(n-1) global_sum += result return result ```

```python def factorial_impure_mutable(n, memo={}): if n in memo: return memo[n] if n == 0: result = 1 else: result = n * factorial_impure_mutable(n-1, memo) memo[n] = result return result ```

```python def factorial_pure(n): if n < 0: raise ValueError("Factorial is not defined for negative numbers") elif n == 0: return 1 else: return n * factorial_pure(n-1) ```

Both A and B are pure functions.

Q3Domain Verified

In "The Complete Python Pure Functions Course 2026," the concept of "referential transparency" is crucial. If a function `f(x)` is referentially transparent, what can we reliably infer about its behavior?

The function `f(x)` will always execute faster than any other function with the same input.

The function `f(x)` will produce the same output for the same input `x` across all executions, regardless of the program's state.

D) The function `f(x)` can only accept immutable data types as arguments.

The function `f(x)` is guaranteed to have no side effects and can be safely memoize
