Python Coding Challange - Question with Answer (01060825)

 

Let's break down the code step by step:

def clear_list(lst):
    lst.clear()

• A function named clear_list is defined.

• It takes a parameter lst, which is expected to be a list.

• Inside the function, lst.clear() is called.

  • The .clear() method empties the original list in place — it removes all elements from the list but does not create a new list.

---

values = [10, 20, 30]

• A list named values is created with three integers: [10, 20, 30].

---

clear_list(values)

• The clear_list function is called with values as the argument.

• Inside the function, the list is modified in place, so values becomes [] (an empty list).

---

print(values)

• Since the original list values was cleared inside the function, this prints:

[]

---

✅ Final Output:

[]

💡 Key Concept:

• Methods like .clear(), .append(), .pop(), etc., modify the list in place.

• Because lists are mutable objects in Python, passing a list into a function allows the function to modify the original list, unless the list is reassigned.
