Python Coding Challange - Question with Answer (01240525)

 

Step-by-Step Explanation:

1. person = "Bob"
   A variable person is assigned the string value "Bob".

2. Calling change_name(person)
   The function change_name is called with person as the argument. So inside the function, name becomes "Bob" (a copy of the string).

3. Inside change_name
   This line:

   
   name = "Alice"

   reassigns the local variable name to the string "Alice".
   However, this does not change the original variable person outside the function.

   • In Python, strings are immutable.

   • When you pass person to the function, you pass a copy of the reference to "Bob".

   • Reassigning name to "Alice" just makes the local variable name point to a different string.

   • The original person variable still points to "Bob".

4. print(person)
   This prints "Bob" because the original person was never changed outside the function.

✅ Final Output:

Bob

---

 Key Concept:

In Python, immutable types like strings cannot be changed in-place.
Reassigning a function argument only affects the local copy, not the original variable.
